MagAO-X 2023A Bonus Feature: Santiago de Chile

I didn’t get into academic astronomy to travel, but I didn’t get into academic astronomy to avoid travel, you know what I mean?

I’m bringing the good ship Ph.D. into port in the very near future, and I have been to Chile some six times (should have been more, but thanks covid) without having seen more than observatories and airports (again, thanks covid).

After a month away from home I was exhausted and had a to-do list as long as my arm, but I decided if I didn’t take some personal travel now I never would. In the spirit of MagAO-X 2022B Day 3: An astronomer’s guide to Valparaíso, Chile, I present 2.5 days in Santiago de Chile.

I gratefully acknowledge the advice and suggestions of Dr. Matías Díaz (lately of drone-piloting fame) and the MagAO-X Chilean Cultural Attaché Dr. Susana Henriquez.

Day 0:

On Sunday the 19th, we left the observatory. A van transported us and the luggage of a one-month stay (multiplied by four people) from Las Campanas down to La Serena airport.

We obtained Kunstmann Torobayo (times four) and papas fritas, as is tradition.

After a short hop to Santiago airport, I parted ways from the rest of the MagAO-X team.

MagAO-X 2023A Day 23: Until the very last photon

This is the time of night an astronomer’s workday would be in full gear, but dear reader, your favorite astronomers are all home or tucked into their LCO beds, dreaming sweet dreams. The MagAO-X team, working 24 hours since you heard from us last, have observed our last target, removed our instrument from the telescope, safely trucked it to the clean room, and started to pack it away for its long trip back home.

In this great relay race, Jared, Sebastian and I were the night team. As the rest of our team hit the hay around midnight, our noble observing efforts were met by some of the worse seeing of the run (after 22B, we do feel lucky to only have one or two nights to complain about, instead of the whole run). Around 1, Jared jinxed us with “At this rate, it’s going to be terrible all night and clear up to 0.5 arc-seconds right before we try to close.” In the great cosmic comedy the universe plays on worn-out astronomers, turns out he couldn’t have been more right:

Hitting 1.5as and 0.5 on the same night…

Seems like LCO weather agrees with my high school track coach, you can’t give up the race right before the finish line. So the night team observed until the sun declared our time up, and only then did we begin the task of shut-down and de-cabling.

The mega monitor, without anything to monitor.

We passed the baton to Laird and Joseph around 8 in the morning, and I’m told that the craning, carting, tethering, trucking and boxing all went well. I can only tell you what I heard because once Jared gave me the all clear, I sleepwalked straight down the hill into bed. Though I was solidly asleep for the rest of the day-time packing work, the successes did not go undocumented:

MagAO-X on the move
aaaannnd…. safe!
Optics: bagged and locked

Right before dinner, when I finally woke up, we were much further along into packing than Jared had feared we would be. Huge thank you the LCO crew who got us off the telescope so quickly, then helped us even more this afternoon to get MagAO-X in its shipping box. After a leisurely meal, the AZ crew headed back to the clean room and started corralling our doodads into the right corners.

We start again bright and early at 8:30am to finish prepping ourselves and the instrument for the long flight to Tucson. Think of us, as we all try the magic trick of switching to a day schedule on a days’ notice.

With things going smoothly, we seem to now have this mythical thing called “free time” and with it the team sneaked in a little wildlife spotting:

Good morning, Guanaco! from Joseph
Farewell, fox family! from Jialin

With these fancy new phone cameras, some team members are getting particularly good at the artistic type of astro-photography:

But wait! Where did Jialin and Jay go?? Rumor has it they got out just in time, and are having plenty of good adventuring before their 24hr journey to the US. Travel safe friends! See you Tucson.

Some pre-airport fun

Song of the day:

As we watched the seeing mysteriously dip last night just as we thought about calling it, Jared goes “you know that song, the Wellerman”? To Jared’s surprise and chagrin, I had completely missed the entire TikTok trend of covering this New-Zeland Sea ballad. It became popularized by Scottish singer Nathan Evans around 2021 but the original tune can be tracked back to the 1830s. It loosely follows a Moby Dick-esq narrative of a whaling ship being dragged along by an unattainable whale. Jared goes on to explain that the tantalizing 0.5 arc second seeing is our white whale, dragging us on until the last possible photon. With the night and the run ending, this felt more true than ever.

“The Wellerman” seems like a fitting song of the day, and of course I have heard it, all it took to remember was a quick search. How could I forget it? I love a good folk tune… love a Scottish accent… but wow I love a old sea song! What the conversation with Jared reminded me of is that, though I don’t really care for metal, heavy metal, etc… I LOVE Pirate metal. People yelling in general angst? I’ll pass. People yelling about the high seas? Sign me up. A fellow friend in the AO research field and bassist in their own right introduced me to Alestorm a few years ago, an Scottish band that exclusively does pirate metal. I haven’t gotten to see them in concert… YET, but I take this band as the single most impactful recommendation music-wise I’ve ever gotten. So in honor of our telescopes and how successful this run has been, I’ve picked their song “Magellan’s Expedition” for today.

As a bonus, here is Alestorm covering “The Wellerman” because of course they did, everyone covered it, even Kids Bop 2022.

MagAO-X 2023A Day 22: Above and beyond

This evening Dr. Matías Díaz, a support astronomer here at Las Campanas Observatory, helped us take a next-level team photo.

Thanks for taking the video with your drone, Matías!

Of course, we have more people in our group than pictured, and by the time we visit again in 2024A (!) we’ll probably have even more new members. By then I will have decamped for the Flatiron Center for Computational Astrophysics in New York, but it’s famously hard to see stars there. Maybe they’ll invite me back.

It’s our last night on sky, which is always bittersweet. Tomorrow’s a long day of removing from the telescope. So, what have we got to show for the past 22 days?

  • 14 terabytes of high-contrast astronomical data (and counting)
  • a new observing mode that keeps light where it should be, allowing us to pass these savings on to the consumer (shout-out to Ms. Lowfs)
  • a handle on our induced DM ✨sparkles✨, which will let us unravel the profound mysteries of pyramids (thanks Eden McSparkles)
  • a lot of improvements to VIS-X (gaan met de banaan, Dr. Haffert)
  • one new extreme-AO-fed instrument (shout-out to Noah & the Ex-Kids, opening for Weezer on tour this summer)

We’re about to commission our knife-edge coronagraph, but this blog post can’t wait. It’s time for the prospective students to choose their Ph.D. institutions, and we must put our best foot (feet?) forward.

Song of the Day

“Anemone” by Brian Jonestown Massacre

I went to a liberal arts college, which makes some people assume I didn’t study physics or something. In fact, astronomy is one of the quadrivium of artes liberales, and my college had a Department of Mathematics and Astronomy before it had a physics one. It’s physics now, though. So there.

Still, a smaller student body and more flexibility in courses of study meant some interesting cross-pollination between departments. One of my classmates in Advanced Intro Astronomy was named Maurissa, and she was actually a music major. She took astronomy with us, but she also had a band, did stuff with electronics, and was in a Balinese gamelan ensemble. Anyway, she was the one who introduced me to Brian Jonestown Massacre, the above psych-rock band with good vibes.

Bonus Song of the Evening

Sometimes you don’t need something musically interesting, and swoopy synths suffice. Anyway, the blog title reminded me, and after all—we are almost home.

MagAO-X 2023A Day 21: The Wind Down

Whelp, it’s getting to be that time. The sun is rising as I type, and it’s officially the 16th. Tonight is our last night on the Clay for 2023A, and tomorrow morning we tear it all apart, box it up, and GTFO.

Another night of awesome seeing let us all catch up on some coding and analysis.

Several coronagraphs where harmed in the making of this image (or at least made to deliver).
And note that none of us were the ones actually studying.

The conclusion of my concert story, which started with the surprise KoRn and went though an awful Marilyn Manson performance, is the band we actually went to see: Danzig. It was every bit as good as one could hope. We were right in front for the whole show. At one point Glenn Danzig reached out and clasped Ben’s hand – legendary. Here is Danzig’s iconic “Mother”:

MagAO-X 2023A Day 20: Extreme Anarchic Observers (ExAO)

Obligatory aesthetic image of the sky/telescope as the 1st image of my blog posts 🙂

Recently, a tragic event occurred on the mountain and I am here to tell the tale of the “Empocalypse.” It all began with a hungry astronomer who walked into the kitchen, ready to heat up the favorite meal of the crowd… Upon opening up the fridge that was supposed to be filled with a mound of carefully wrapped empanadas, the astronomer discovered a fridge devoid of empanadas. As the news went around the telescope, the cries of the grieving observers filled the rooms. The empanadas are one of the few things that hold value within the MagAO-X group while we are at LCO, and their sudden disappearance almost started a riot. The dissatisfaction has been reported to telescope officials and hopefully, it will be taken seriously. On the brighter side of things, since the calamity, the snack selection has increased, one of which being a miniature version of the hangry astronomer’s favorite.

Mini Tritons and its #1 fanatic

On the contrary, we have been treated well on the science side, some might even say spoiled. The seeing read by Dimm dropped below 0.3″, which is a rare occurrence. The TO even called his buddy over to witness such an event. Just when we thought the night would continue to have spectacular seeing and a smooth sail, the seeing doubled by midnight. However, great spectral data were still taken with VIS-X.


Per the title of the blog post, I feel obligated to continue to share other moments of this run that embodies similar energy. Well, truth be told, I am feeling like an ExAO, thus, I am writing a blog post full of content that is deserving of some love and attention (according to me, BAHAHAHAHAHAHAHA!)

We have our second special visitor in the telescope. This bird scared me more than the occasional “Chicken Nugget.” In addition to almost giving me a heart attack, it brought a special gift of bird dropping. It was our unsung hero, Jay, who cleaned up after the surprise visitor.


As we are nearing the end of this observing run, it would not be proper to think the kids can still be considered “normal.” Ok, maybe I should only speak for myself, but I do have some evidence of abnormal behaviors.

Song of the Day

During my last visit here in December, my music app of choice sent me a recap of my 2022 music journey. My top album was “Bad Mode” by Japanese Artist Hikaru Utada and its title track is my chosen song of the day. I first discovered them a decade ago through my older cousin’s iPod playlist, and ever since, their songs have been on my playlist. As they have risen to fame and become less active way before I was a fan, I have not been able to catch their live performance. It is, however, on my bucket list to be at their live performance at least once.
