Personal Panoramic History, Part 5: 2012

The previous post in this series (covering 2011) had quite a lot pictures, but for whatever reason 2012 was a pretty slow year in the panorama department. I think part of it was that I was working at the Visitor Information Station on Mauna Kea for most of that year, which was also the year the transit of Venus happened. I was pretty quite preparing for it and then recovering from it afterwards, and it seems to have translated into fewer photo opportunities.

In January 2012 I got my first smartphone (a Samsung Galaxy S2), and with it my first automatic panorama creation ability. I didn't actually use it much because it was still pretty poor in those early Android versions, but I've got a few panoramas made using it from this year and we'll see more in the future.

April


My first panoramas of the year don't come until April, but they come from the one time (so far…) that I've hiked Mauna Loa. And just as while hiking Mauna Kea I got pictures of Mauna Loa, so while hiking the latter I turned north to get pictures of the former.

Mauna Kea from the south.

Hualālai and Mauna Kea
 These two pictures are both from where the trailhead starts, just outside of the Mauna Loa Observatory entrance at 11,141 ft (3,397 m). The first one is a zoom-in on Mauna Kea, while the second is a much wider field view covering a bit less than ~180°, showing the Mauna Loa access road on the right and the start of the trail on the left.


Mauna Loa summit caldera.
Mauna Loa is so flat that while climbing it there isn't much to get panoramas of other than Mauna Kea, until you reach the summit caldera, Moku‘aweoweo. This panorama is still pretty cool to me, even if we didn't make it to Mauna Loa's summit that day, as it's technically the only time in my life I've been inside the caldera of an active volcano! (Even if it did last erupt in 1984…) You can see the sides of the caldera on the sides of the photo, as I climbed down just inside the rim (which was maybe three meters deep). I don't think this is a particularly great panorama, but it's special to me due to the circumstances surrounding its creation.

June


Venus transiting before the Sun.
In June the latest transit of Venus (last one until 2117!) happened. This panorama is hand-made, as I couldn't get Hugin to make one for me using my photos. It's not really meant for astronomical panoramas and the photos aren't particularly well-focused either, so it's understandable that it failed to make anything of them.

August


I didn't get around to making any more panoramas until August due to recuperating after the transit of Venus, and when I did I ended up taking my first auto-generated panoramas with my phone due to (as usual) my camera battery turning out to be dead. I was able to get a tour (I think with the University Astrophysics Club) of the Very Long Baseline Array dish on Mauna Kea, and it turned out to be a great panorama subject.

These early auto-generated panoramas are really ugly however, so I'm only going to show one to give an idea. I've got a few more, but I just don't feel like displaying them here; that early panorama creation software was pretty rough and the resulting images are not easy on the eyes. I did put two additional panoramas from this trip up in my original post about it, so you can follow the link if you really want to see more early auto-panorama creation eye-sores.



This is the dish of the VLBA telescope, from near it's rim. Which is about ten stories above the ground, by the way. I'm actually amazed the camera was able to get such a good contrast, considering the blinding whiteness of the dish.


And that's actually it for panoramas from 2012! In October I did lava tube spelunking for the first time and got some cool pictures, but lava tubes unfortunately don't make great panorama vistas. As the end of the year approached I was starting to get pretty burnt out at my job as the Visitor Information Station; I discovered that there's a vast difference between doing something as a volunteer because you love it, and doing it because you get paid to do it. On a whim I applied to a job with the James Clerk Maxwell Telescope that only required a Bachelor's degree, and near the end of November got a call saying I was being offered the job, which opened up a whole new chapter of my life. But that's for the next post! A hui hou!

April Astrobite, a Supercomputer Tour, and Other News!

So this is a few days late, but I wrote another post for Astrobites this month back on the 12th. It covers a really cool paper about the largest flare yet observed from Proxima Centauri, the closest star to the Sun. Proxima Centauri is a red dwarf, the most common type of star in the universe, but also the faintest; it emits a mere 0.17% of the light the Sun does, and despite being the closest star at just over 4 light-years away normally sits at about magnitude 11.13, or over a hundred times fainter than can be seen with the naked eye. However, during the flare reported in the paper, the authors calculate that it would have briefly reached up to magnitude 6.8, making it just barely visible to the naked eye from a very dark site for a few minutes! Pretty nifty! I even got an email from the lead author on the paper saying he'd enjoyed my summary of it, so that was nice.


In other news, I was fortunate enough to tag along on a tour of Swinburne's new supercomputer. (We are the “College of Astrophysics and Supercomputing,” after all!) It's called OzStar and replaces an older supercomputer called G2, though that one will still be in operation for most of the rest of the year to give people time to switch over.

OzStar, CAS's new supercomputer. I don't actually have reason to use it myself, sadly.


Going through all my photos in my panorama series, I've been struck by just how many photos of random birds I take. So have another one of some really colorful parrots I found in a eucalyptus tree near where I live one day while walking!

Parrots! Really colorful ones, too. These pictures are all from my new S9+, by the way.


And finally, one thing I haven't been able to find here in Australia is my favorite salad dressing, Hidden Valley Ranch. You can get Ranch dressing here, but there's usually only a single kind on sale. One of my friends from church was in the US for a few weeks as part of a school trip and very kindly brought me back the ambrosia below:

Just can't beat the original.


I also gave my first public Astrotour at Swinburne last week! We have a 3D theater that is used primarily for public outreach with grad students and faculty who volunteer giving talks to both school groups and the general public. I signed up last year, and gave my first talk to a small public audience last Tuesday. I felt rather rusty and disjointed as it's been so long since I gave a public talk about astronomy, but all that practice at the VIS paid off and it seems to have gone well. I've got another scheduled for the 30th of April, though I think this one is a school group, so that'll probably be a very different experience.

And I think that's all so far for this surprisingly busy month. Oh yes, last week I finally managed to write some code that collated some information on atomic transition lines that we've been trying to get together for a few months now, and this week we sent them off to some collaborators to do some calculations for us. So that's a huge weight off my chest. A hui hou!

Personal Panoramic History, Part 4: 2011

In the previous post in this series we looked at a whole bunch of panoramas of Mauna Loa. In 2011, in contrast…okay, I can't lie, we'll see a few more panoramas of Mauna Loa. If ever there were mountains made for panoramic viewing, it's Mauna Kea and Mauna Loa. But! We'll also see some new and unique vistas which for various reasons I haven't had the chance to recreate.

2011 was the year I finished college and graduated from UH Hilo, and thanks to all the volunteering I'd done at the Visitor Information Station I had a job lined up to start there in 2012. But for now, let's get on to the pictures…

January


In January 2011 my housemate Jonathan and I decided it'd be cool to try to get some photos of the Sun rising out of the ocean from Hilo. It took us several trips to various locations around Hilo at the crack of dawn over the course of a few weeks to realize that the joke was on us: there are always clouds away off on the eastern horizon around Hawaiʻi. So we never did get the pictures of the Sun rising majestically out of the ocean like we wanted, but at least I got this first light panorama of Hilo Bay out of it (unintentionally, I only found and put these photos together while writing this post):

Mauna Kea over Hilo Bay. Coconut Island on the right.
This panorama from the morning of January 17th shows Mauna Kea, resplendent in the pre-dawn chill, with Hilo stretched out along the left side of the image and Coconut Island on the right. You can probably only see it if you already know what you're looking for, but you can see the breakwater that protects the bay stretching along the horizon behind Coconut Island on the right side of the picture. It looks like it may have been raining north of Hilo and further up the slopes of Mauna Kea that day.

February


On February 22nd I hiked the summit trail of Mauna Kea (down) for the first (and so far only) time as part of a volunteer effort to pick up trash and keep the trail clean. (As before, you can follow that link and mouseover the panoramas in the post to see the original hand-made versions.) This allowed me to get a panorama of a rather different body of water:

Lake Waiau.
This is Lake Waiau, at an elevation of 13,020 feet (3970 m) making it one of the higher lakes in the world (though it depends strongly upon which list of lofty lakes you consult, as there's no official definition of what a lake is). I did originally have a picture of the right hand side of the lake (its north end, from this perspective), but somehow lost it in the process of transferring the photos from my camera to my computer all the way back when I made my first, manual version of this panorama. I have another panorama of this lake, but that's for a future post!

Mauna Loa, from part-way down the south slope of Mauna Kea.
And here's our first Mauna Loa panorama for the year, from somewhere down the trail. The summit area of Mauna Kea is so broad and flat that it can be hard to remember you're on top of a mountain sometimes, but as you descend you reach some (moderately) steeper bits that allow you look down and see the Saddle region spreading before you, with Mauna Loa in the distance. If you look closely you can even just make out Hualālai peeking over the hills on the right. This is definitely another one of my favorite panoramas I've taken.

June


On the 12th of June I had the opportunity to hike to the actual summit of Mauna Kea, something I've only done three or four times over the years despite being in the general area more frequently. (It's not a long walk, it's perhaps ten minutes or so from the closest road, I just never usually had time when I was up there due to other duties.) Whenever I had the chance to do so, however, I'd always discover that I had either forgotten my camera, its batteries were dead, or the weather was so bad that I couldn't get pictures (it wouldn't be until January of 2012 that I got my first smart phone, and I had no way of getting photos off the phone I had before that).

Except this time. For once I'd remembered my camera, it still had battery power, and the weather, though not great, was good enough to get this panorama:

Mauna Loa and Mauna Kea summit.
This may be the only picture on this blog from Mauna Kea's summit, at the rarefied height of 13,796 feet (4,205 meters). This view stretches from looking east on the left down towards Mauna Loa to the south. As you can see the weather was not particularly great that day, with lots of cloud cover both around the slopes of the volcanoes and also much higher up. The cinder cone bowl seen in the foreground on the right of the image is Puʻu Wēkiu, wēkiu meaning “summit” in Hawaiian. The summit proper is simply the highest point in its rim.

I really wish I'd done a 360° panorama for this one. Oh well, future life goals I guess. Someday when the weather's better would make a better picture anyway.

July


Come July I was once again back home in California visiting family, and my mom's family had a reunion up in Washington so we drove up through Oregon to attend. Along the way we stopped at some pretty nifty places, and I was able to get a few panoramas out of it (only one of which has shown up on this blog before).

One of the places we stopped was Crater Lake inside Mount Mazama, which is a fabulously cool place to visit. Despite visiting in July there was still plenty of snow piled high in places.

Crater Lake, with Phantom Ship visible.
This simple four-photo panorama comes from somewhere on the south-eastern side on the rim of the massive caldera that makes up the lake. Visible near the bottom-center is Phantom Ship, the smaller of the two islands in the lake. This and the next panorama were only created while writing this post, so they're new to me as well!

Crater Lake, this time with the much larger Wizard Island visible.
This panorama comes from the walkway heading towards the Visitor Center which provides an overlook of and lots of information about Crater Lake itself. In this shot the much larger Wizard Island near the western side of the lake is visible. The lake is 1,949 feet (594 meters) deep at its deepest point, yet Wizard Island still towers an additional 755 feet (230 meters) above its surface! It's a cinder cone formed in the caldera after the monumental eruption that dropped Mount Mazama's height by nearly a kilometer and created the original caldera.

Crater Lake with Wizard Island again, from the Visitor Center.
Finally, this panorama is one I've shown before, though this version was created with Hugin rather than by hand (you can compare the two by mousing over the image in the linked post). I really didn't write that much about Crater Lake when I visited it, which is a shame because it's a fascinating place. Especially after living in Hawaii for a few years and becoming acquainted with volcanoes.

For instance, Crater Lake is the deepest lake in the US, the ninth deepest in the world, and has some of the clearest water of any natural bodies of water anywhere. And the scale is simply mind-blowing: Mount Mazama was estimated to be about 12,000 feet (3,200 meters) high before its fateful eruption; the highest point on the rim is now 8,159 feet (2,487 meters). A beautiful and poignant reminder of the raw energy of the natural world.

Another place we stopped after visiting the lake was the John Day Fossil Beds National Monument, Painted Hills Unit. (Hooray for taking pictures of signs so I know where it was!) These two panoramas were both two-photo accidental panoramas that I only discovered while writing this post.

Painted Hills, Oregon.
The landscape was truly spectacular. I wish I'd created more panoramas while I was there, as there was no shortage of subjects.

Oregonian bluff.
I'm not sure what this bluff is called (if anything), or where it is exactly—all I can tell is that we took a few group photos in front of it after I got this panorama and it appears to be near where we ate a picnic lunch. It's a great representative of the landscape in the area, though!

September


September found me back in Hawaii, taking pictures of the same familiar subjects once again: more Mauna Loa panoramas! Seriously, I'll have to count how many different ones this single volcano's featured in when I finish this series…

Mauna Loa.
This panorama and the next are reminiscent of a similar one from 2009 seen in part 2 (though here the grass is brown and dry). Possibly an attempt to recreate it, as the 2009 version is one of my favorite panoramas I've taken. Don't look too closely at those fence wires, they kinda pop in and out of existence near the bottom of the image. I imagine close-in fine details like that are difficult for Hugin to deal with when there isn't enough photo coverage and the perspective changes rapidly.

Mauna Loa, again.
This panorama (from a zoomed-in perspective) is the Hugin version of a panorama I originally created manually whose existence led me to discover this forgotten post where I'd already shown off the manual version but forgotten to apply any tags. Don't look too closely at the barbed wire in this one either.

Mauna Loa, from just outside the Keck building.
This two-photo mini-panorama comes from outside the Keck building, though it doesn't show much other than Mauna Loa in the background and some of the so-called Sub-millimeter Valley where the telescopes sensitive to light with sub-millimeter wavelengths reside. You can see CSO in the middle, and some of JCMT on the right. Pretty sure this wasn't planned to be a panorama originally or I'd have taken photos with a wider coverage.

November


On November 4th the University Astrophysics Club was able to get a tour of Gemini North, the InfraRed Telescope Facility, and UH Hilo's own Hōkū Keʻa telescope. This trip is the snowiest it's been up at the summit while I've been up there, which makes for some great images! The first two here I only created in the process of writing this post.

Snowy Mauna Kea summit, overlooking Submillimeter valley.
Another shot from outside Keck. (I'm not actually sure why, as I don't think a Keck tour was part of our itinerary—I don't have photos from inside it, anyway.) The snowfall must've been recent, but fairly light. (And judging by the distribution, must have come from the west, maybe? This is facing south towards Mauna Loa.)

Mauna Kea's snowy North Plateau.
This one's kinda interesting. It looks like it came from near IRTF, and is facing north over the North Plateau (where TMT, if it ever gets built, is slated to go). I don't usually take too many photos facing north like that, especially if the weather isn't clear and Maui isn't visible.


From a few weeks later (November 27th, to be precise) comes this panorama of Mauna Kea and Mauna Loa. Though it may not look it, this one is actually from a (slightly) different location to the others that have shown up so far. On the left of the image, between the peaks of Mauna Loa and Mauna Kea, you can see the peak of Puʻu Kelepeamoa, where several of these panoramas have been from. That peak, however, is merely the highest point in the rim of a giant cinder cone just below the Visitor Information Station (so large, in fact, that the Access Road runs through it). This panorama was taken from the second-highest point in the rim, on its eastern side. (Puʻu Kalepeamoa is on the west.)

In the original hand-made version of this panorama (visible at the link above) I put Mauna Loa on the right of Mauna Kea (possible as it's one of my rare full 360° panoramas), but I think this composition works a lot better.

December


In December of 2011 I graduated from UH Hilo (or technically, I participated in the ceremony, a slight miscalculation with paperwork meant that I didn't officially graduate until next semester). Also my family came out to visit for the first time! We did some sightseeing while everyone was there, and I have a lot of photos, but I could only find a single accidental panorama, from a botanical garden we visited a ways up the coast north of Hilo:

Hawaii Tropical Botanical Garden, looking out onto Onomea Bay. Don't look too closely at the middle palm tree.

And that's it for 2011! A pretty good year for panoramas, all told. The next post's going to be pretty short as I really didn't take too many panoramas in 2012, not even accidental ones to be discovered after the fact. There're a few good ones, though, and starting in 2012 there'll be ones taken with a phone camera—they're pretty awful at first, so it'll be interesting to watch them improve over the years. A hui hou!

Vegemite

As the saying goes, “when in Oz, do as the Aussies do,” (or was that Rome? No matter) and as a result I've taken to eating Vegemite. I was actually given some to try my fourth day here, and it's really not half bad, certainly not as bad as I'd been led to believe…if taken in moderation.

For the sake of any of my fellow Americans who decide to try it, I've attached the following picture to show you how to apply it:

  1. The slice of bread on the right has butter. This is what you want for your base.
  2. The slice on the left has butter, and less than the size of a pea's worth of Vegemite. This is the correct amount to apply. Actually, even that may be a bit thick. A little goes a very long way.
  3. The slice in the back has Nutella. Do not apply Vegemite that thickly. It will not end well for you.
The best description I've heard is that Vegemite is basically like spreadable soy sauce, and it's an apt comparison: both are extremely salty foods that can spice up otherwise-boring foodstuffs if applied in moderation. It'll probably take me about forty-seven years to get through that jar at the rate I eat it, so I should be set for life. Let me know in the comments if any of you have any personal experience with Vegemite! A hui hou!

ἠγέρθη! He Was Raised!

ἠγέρθη!

Matthew, Mark, and Luke all record this same angelic utterance in their respective recountings of the Resurrection. (It's pronounced ē-GER-thē.). If we parse it we get third-person singular aorist passive indicative, “he was raised.”

The aorist tense gives the action the perfective aspect, a single unit of completed action, without internal structure or ongoing duration. Jesus was raised, over and done.

The passive voice indicates the subject being the recipient of the action and reveals the Divine agency latent in the Resurrection; Jesus was raised by the Father, not of his own agency.

And finally, the all-important indicative mood, not the "possible" or "potential" of the subjunctive or optative moods but the factual actuality of reality. Jesus was raised! Happy Easter everyone!
