MagAO-X 2024B Day 14: More Treats than Just Empanadas

This Sunday, we celebrate the triumphant return of the penguin seeker, Dr. Joseph Long, along with his bonus blog detailing his short weekend journey. On top of the cute penguin pictures, Joseph brought back lots of local chilean snacks that he sourced in supermarkets during his trip.

As always, before the sunset viewing session, a few of us went out for a vizzy spotting session. We only spotted a little baby vizzy and we were unable to find the parents. I suspect that we have been coming to this spotting location too often and have scared some of them away. As requested by a follower of Jay, we recreated the famous “crawling Jay, searching for vizzy” moment.

Roger, our T.O. for this turno, marched towards the dome with another basket full of empanadas in the glow of the setting sun as we gathered outside the control room for another sunset viewing. Although not captured by a phone, we were fortunate enough to witness another green flash on a Sunday this run. “Do you get deja vu” feeling that I am getting?

Tonight on the observation schedule, we have Sebastiaan and Alycia. Some errors popped on CACAO, but were “successfully ignored” and we went to observe giant stars with low resolution mode on VIS-X and regular imaging mode on MagAO-X.

As the time for midnight lunch approaches, Joseph cracked opened some of the snack that have arrived on the mountain today. Katie, our resident Canadian snack tester, had particularly strong feelings about the ketchup flavored cheetos. As a big fan of the Canadian ketchup chips myself, I would have to agree with Katie on this one. Unfortunately, I have another disappointing news to deliver: the empanadas today contained 300% more olives than previous Sunday.

With the successful engineering blocks in the past few days, Sebastiaan implemented partial EFC on sky for Alycia and Jay’s debris disk observations, which dug a dark hole for seeing fainter objects like disks.

Song of the Day

Per the 24B blog rules, the song I have chosen for the day is “déjà vu.” We are constantly doing new. and exciting science on the mountain, so I “think everything is special”.

MagAO-X 2024B Bonus Blog: Once more with penguins

It’s been a long-time dream of mine to see wild penguins. I have previously been thwarted by scheduling conflicts, pandemics, and the simple preference for being home after a month away rather than prolonging my travel further… but enough is enough. Once Maggie and Katie managed it, I had to get my act together and actually plan an outing. Due to scheduling constraints, this required me to steal away in the dead of night.

It’s much easier to plan such an excursion from the Las Campanas Observatory El Pino office than from the observatory itself, so I went to bed early, got up during the day, and rode down the mountain. El Pino lacks the food options of the lodge, but has an actual address you can give to people to come pick you up. The new rooms aren’t half bad, and they have a great view of La Serena… or they would, if someone had put a window in the southwest wall of Room #5.

It is generally understood that the main reason for us northern-hemisphere types to travel south of the equator is to see penguins in the wild. (The explorers of old also noticed the constellations look kinda funky down here, but they’re probably just upside down or something.) These graceful and intelligent animals are found all the way up to the equator, but no further. Different species of penguins have evolved to adapt to different climates, making them available in a variety of fun flavors. Most penguins are flightless, but this blog records one exception.

The Antarctic Emperor penguin is, sadly for us, not visiting the 29th parallel. However, the Humboldt penguin is perfectly happy noodling around at the same approximate latitude (29°15′31″ S) as our beloved Magellan Telescopes (29°00′54″S). Their longitude, of course, differs. (This results in the penguins computing a different local sidereal time for their telescopes.)

Maggie covered the logistical particulars of this excursion well enough, so I won’t reiterate them here. The gist of it is:

  1. Take car from La Serena to boat.
  2. Take boat to penguin preserve.
  3. Take photographs.
  4. Provoke jealousy (optional).

So, without further ado, pingüinos:

I lack a telephoto lens so there was a bit of optical alignment required between my phone camera and binoculars for most of these photos. Note that the penguins are very small because they are far away and also because they’re very small.

There were also some other goofy dudes.

And on the way back, a family of dolphins came to play by the boat!

After returning to shore we also stopped at a spot exhibiting tour group—Andean fox symbiosis. They trotted right up when we pulled over, expecting treats.

Note that we did not feed this fox. Mind you, someone‘s been feeding them.

One benefit of spending two nights down in La Serena was that I could restock our observing snack supply. The Magellan Clay break room has been kept well stocked with biscuits and The People’s Cheese, but one eventually craves variety.

Visiting grocery stores is one of my favorite things to do any time I’m in a foreign country. I believe you can learn a lot about a place by what people snack on. However, some things provoked more questions than answers.

Why is Sahne-Nuss the only candy in anti-theft packaging? What are Costco brand nuts (labeled in English) doing here? What kind of flavor is “cola de mono”?

Ponder these questions as you enjoy the…

Song of the Day

I hereby declare bonus blogs exempt from the per-run blog rules, being as they exist outside the blog-time continuum. Also, I don’t think I can incorporate any lyrics from this song in the post.

BUMP OF CHICKEN「天体観測」

(天体観測 (tentai kansoku) does translate as “astronomical observation”, though.)

MagAO-X 2024B Day 13: These are the nights to hold on to

I think I’ve had observing time at LCO in every month (though I’m unable to figure out from the records I have on my laptop if I’ve actually physically been at LCO in every month), but this is the best November that I remember. The days are warm and lovely, the nights are clear and crisp with good seeing. “These are the days to hold on to” and “this is the time to remember.” I’m busy using this run to forget the 2024Ab weather.

Yes, that is seeing on the DIMM below 0.4 arcseconds
This is the time to remember ‘Cause it will not last forever

Even though I never forget how beautiful it here, I can’t help taking more photos of lovely sunsets and Venus next to the dome.

Oh LCO, [you’re giving] me the best of you

A lot of Magellan observations are done remotely now, but I continue to think people ought to come and experience the Observatory and learn the instruments in person. There are no shortage of students on this run, of course, given that MagAO-X is so hands-on. And I admit that I am remotely observing on two separate nights in the next month alone. But I hope some others see these photos and want to come. I fear a future when we’re all just looking at screens of telescopes.

Our Telescope Operator, Roger, doesn’t have to walk into the dome to look at the telescope. “time is gonna change”

On a different subject, I have to say that for something not very funny to 9 people sharing one bathroom in the dome, our clogged baño caused a lot of hilarity. Thanks to the heroic efforts (though I will spare you the photo) of Roger, Laird, and Parker, the situation was resolved. Now we “look back and have to laugh. We lived through a lifetime and the aftermath.”

Thanks to everyone (including the missing Jared) for their help in making this a great MagAO-X run. “You’ve given me the best of you”

Song of the Day: Anyone my age knows the song I’ve been quoting as it was absolutely unavoidable in 1986-87 and possibly the prom theme for every senior class in America in 1987. Magellan wasn’t my first love, but “I’m warm from the memory of days to come.”

MagAO-X 2024B Day 12: Manqui Moon

It’s time to finally call off the searches everyone. Tie up your bloodhounds, turn off those spotlights, and park your helicopters. That’s right, the mountain’s most infamous instrument has been located after eons of searching high and low.

There were fears that MagAO’s near-IR camera, Clio, had been sentenced to the boneyard to peacefully decay as the many instruments before it. However, despite being undoubtedly still weary from her travels, Alycia generously gave the students a nice tour of the DuPont telescope (a.k.a., the 100″) just down the road from the Magellans where they found our Clio and drew collective sighs of relief from all who were around during the golden MagAO days.

Day break, too much light for sleepy eyes

And here it is! The Great Clio! Ready to be born again on another 6.5-meter telescope…!

A special thanks to Prof. Ewan Douglas of Steward Obseratory’s UASAL who was a critical part of Clio’s rediscovery. No need to be humble, Ewan.

Yeah, man. So, after the tour, some of the group decided to make use of some extra time before dinner to prepare for the MagAO-X telescope removal. This Chilean iron is extra dense, I’ll you what. But this dry air will make you soft, so we push on.

Thanks, Elena for serenading us during our workout. Those high notes absolutely helped us push out a couple more reps!

After dinner, Laird, Alycia, and received a nice tour from the LLAMAS team who showed us how the instrument was mounted and talked a little bit about how it all the various systems and mounting fixtures work. 1700 kgs of pure instrumental awesomeness.

The underside of the LLAMAS instrument showing the complicated, but organized network of glycol tubes responsible for the temperature management of the cameras. They use a glycol concentration of 25%, and claim that the glycol should never need to be changed. They also allegedly add a biofilm inhibitor of some sort. Maybe we should try that out?

Some of us got heartier meals for our night lunches than others. Parker’s Pro Tip of the Day is write “extra everything, times ten” on the comment section of your night lunch form to get the homie hookup from the kitchen.

A major milestone in MagAO-X’s career as an extreme AO instrument, Sebastiaan et al. have successfully implemented wavefront sensing and control using a neural network on-sky…! We’ve been learned, people.

In other engineering news, Jared and Eden and I got a 5kHz LOWFS loop locked on one of Sebastiaan’s target for some kick-ass vibration control. Whatcha know ’bout jitter?

Ok, there was actually a lot more that went on tonight, such as Team Jaylycia getting some pro-level data on an edge-on disk. Again, testing the altitude limits of the telescope and the instrument. And probably even more to report on, but we’re pretty…

In a daydream until darkness falls

…sleepy. However, I’ve got one more moment to highlight, as it was the sweetest gesture and gift I’ve received as a direct result of being peanutted. Yeah, somehow peanuts got into my tuna + rice tonight (it was literally just some rice and tuna/shrimp in a white cream sauce) and I took a nasty hit to my health bar. However, one Zyrtec and a bunch of crackers and soda helped me recover enough HP to make it through the rest of the night. Because of this experience, Johnson “The Hook” Johnson crocheted me a “J” protection charm to wear to commemorate my survival. Thanks, man. I owe you some milk.

Song of the Day

I’ve been really into this song during this run. This one really deserves a listen, not only because you all need to see that Warren’s long lost twin brother is a guitar virtuoso, but this guy also pairs one of my favorite music genres (percussive fingerstyle guitar) with a killer voice. Some lyrics found in the body of the post above.

MagAO-X 2024B Day 11: Halfway through

I could feel it from the start: This night was going to be a success. Despite the haze that we could see in the horizon during sunset, the night gifted us a stable seeing and what was cloudy now is clear, baby. Can you believe we are only already at half of the observation run!? Me neither, in fact days and nights are starting to merge in my head by now, and time has turned into a meaningless, fleeting concept. What’s more is that we are really close to a full Moon. Might not be a blue Moon, but the light it reflects still allows for more vitamin D in my body than the one I would get in the Netherlands at this time of the year. Moon, you’re the light that I needed.

Before starting our observations, the pneumatic seal on the secondary mirror had to be fixed, so we had to lower the telescope to 1 degree of altitude to reseal it. You don’t see a telescope do such a big tilt every day!

Tonight was again all about Laird and Jialin and their observations. The driver of tonight was mainly Parker, who was tutored by the more experienced grad students.

We were all really excited about digging digging dark holes, until we realized Laird was using the Lyot mask, but not the Lyot stop. Sebastiaan was very displeased about this. I am therefore obliged to call it control region, and not dark hole, from here onwards.

During the first half of the night we looked for young planets that still have residual formation heat in the iz band. Afterwards, we focused on protoplanets that are still accreting in H alpha. In the meantime, some other folks were working (or testing launch trajectories) on their laptops downstairs.

Finally, I want to acknowledge and thank one of our most affectionate blog readers. Your message really warmed up our hearts today. As a gift, I will show everyone a new animal I spotted today: Carlos!

And you, dear reader, if you are enjoying this blog, spread the word: tell your mother, your brother, your sister, and your friends, don’t let them lose the chance to discover our new song of the day every day.
