Thank you Carla for the wonderful blog post yesterday, and also for taking such good care of us. I of course really mean thanks for delivering our empanadas on Sunday. We’ll see you next turno!

I know it looked like a lot of food, but I was actually somewhat disappointed in our team’s commitment to Empanada Sunday. This tradition at LCO is one of my favorite experiences here, and part of what makes this place so special. I have seen the lounge table tiled with empanadas. A friend of ours even flew home once with her carry-on full of empanadas.

So yes, I ordered 4 empanadas. But that was only because the new night lunch order form limits you to 2 carne and 2 queso. I would have ordered 8. But the trick to hording empanadas here is that you have to defend them.

We said goodbye to Joseph and Warren this morning. Joseph was debugging software while Warren was frantically taking PIAA characterization data until the Sun forced us to close up, and they then ran down the hill to pack and catch the bus. After some sight seeing in La Serena they met up with our fellow Stewardites for the traditional Papas Fritas at the La Serena airport.

On-telescope optical characterization can be pretty draining.

Tuesdays are shift-change day, “turno”, at LCO. So fittingly our departing AOistas passed their relief.

Logan has returned! She managed to stay awake after the 24+ hr journey just long enough to watch the sunset with us.

Some of our crewmates manage to avoid the stresses of cutting edge astronomical instrumentation research, and just go with the flow.

Since the day after thanksgiving one of the features of sunset watching from the Clay telescope has been the intense glow of the lodge Christmas Tree.

I am (Carla) so glad to be at the first and hopefully last night of this MagAOX run.

I was here the last first night too (2022A) and both of them were very chaotic. To add one more word to your chilean vocabulary I hope that I am not the YETA one here. To be Yeta means that every time I am around, bad things happen … but that’s the reason for engineering, to have a looooong time to solve problems. Maybe we will meet again on your next run jujuju.

As TO, there is not much work to do. I am just responsible for centering the field and then you unfocus whatever we do so, the rest of the exposure I have the time to get to know you all better and talk about different things, from science to travel across Chile.

I am so excited about this revolutionary science project that I hope to see you over the years and to continue learning from you. This week I learned a lot about the coronagraph. I have never had the opportunity to see this in action, it is exciting so I wish this works better every time. And thus I can read more about your science results. I never told this yet but I have an astronomy outreach project for BVI people, so I want to absorb all of your knowledge to make a tactile model of something new. This is my secret plan through the week xD.

I love your spirit, even when the things are not working or you have problems with the installation or something doesn’t fit or the ADC is bothering, somebody in the room finds the right solution or the right joke that raises and spreads the energy that we all need.

Just want to highlight one fun fact that I have never expected. During these 4 days I need more than one canasta to transport all the food from the hotel to Clay. Especially on Sunday, the kitchen staff prepare two whole trays full of empanadas and meals for all of us. Thank you for helping me carry all the food these days.

I really look forward to meeting you again in 2023A. I wish you a nice trip back home, a very good and deserved break for all of you and a very happy holidays. 

PS: I hope to remember to bring you chilean candies for the next one!

PS:: We are at Clay jujuju.

Song of the day:

The beauty of astronomy is the geographical union through the world atlas. 

After the embarrassing fate of only the 3 professionals at the helm yesterday, our elders decided that today was the day to teach the youth how to run things. So this post is by and for the young ones. I took the reigns of the AO correction Mega Desk and closed a loop on my own for the first time on sky!

What is my actual project here? I’m syncing! (and it’s even going alright.) As of today we’ve set up a function generator to guide our wavefront sensing camera. Right now we are just using it to remotely stabilize the acquisition rate for the pyramid WFS camera, but eventually we will connect the pyramid modulator and WFS camera for applying incoherent speckles.

On the LOWFS side, Avalon successfully closed on nine modes in Z-band. But is still battling the good fight against speed. The team is planning on testing again with the camera going faster, which will hopefully will help them towards defeating the plague of astigmatism.

Her continued experiments are not the only thing that makes her a star grad student. She also was the finder of Jared’s glasses, which he had already searched the whole mountaintop for.

Jialin, after a few day’s heroic efforts on our observing schedule, got to her first science target tonight. Though seeing deteriorated, we were still able to get several hours of well corrected data and even resolved a disk.

Warren continues to survive marathon PIAA alignments, conjugation errors, and testing. Today he worked further at better alignment and characterization, but did not respond to requests for further comments.

Our merry crew continues to chug along, as our engineering nights start to transition to science and our system is better prepped than ever.

Finally, our first science result of the run, an extended source brought to us by Dr. Haffert that we collected yesterday.

Song of the Day:

From a dad rock get away to having the whole world on your shoulders.

After an eventful 24 hour day, a record might have been broken at the Las Campanas Observatory; we have welcome 3 more University of Arizona scientists, making a total of 12 Arizonians on the Chilean mountains.

Second night on sky began with the customary group sunset viewing photo taken by UA Professor Xiaohui Fan.

With Avalon’s efforts, 10 low order wavefront sensing modes were closed on sky for the first time! “10 might not seem like a lot, but don’t most close on 2?”

Science targets were observed while working towards engineering goals throughout the night. Sebatiaan captured beautiful images of R Aqr. If you’d like to see them, like, comment, and subscribe to this blog to hear the newest updates. Warren continued on PIAA alignment and tested it on a binary, possibly multiple star system, HD 20121.

PDS 201 is the first target observed for the Max Protoplanet Survey on this run. With the great seeing around 0.4, the 3 hour observation through its transit resulted in the total of about 80K high quality images. This also means a grad student will be reducing data happily throughout the next day. And the night ended with some more effort in engineering, characterizing vibration and making Strehl measurements.

While in the kid’s lounge… some might say they are having too much fun.

Since we went on a journey yesterday, let’s go on a getaway today!

From the long days comes an even longer night with the first engineering night of the run. What follows is a brief recount of the 24 hours spent getting MagAO-X running. Today started bright and early with getting MagAO-X up the mountain.

The final 200 meter climb resulted in the instrument finally getting to the summit and installed. The final vertical climb up the elevator was the fastest process of the whole day! It only took a mere 2 minutes, time lapsed in a cool 12 seconds below.

Once on the platform a myriad of tasks were then taken to get it into place. Starting with disassembling the cart and getting it onto the legs. After giving MagAO-X its legs back and getting it into its final position Warren, Eden, and Avalon graced us with this musical number, dubbed “Carol Of The Safety Toe Shoes”, to commemorate the moment.

After this great composition the group aligning the instrument took a break as the Baade telescope posed for us! (It totally wasn’t because of some press)

After seeing BAADE the team took a slight detour into the auxiliary building, specifically to see where the primary mirrors of the Baade and Clay telescope are re-aluminized. The students had fun with the acoustics!

We of course had to be inspected by the burros, they approved of our work.

And finnally after a long day of work the day ended and beckoned forth the night. So, as is per tradition, the team got together and was able to get one final photo with the last vestiages of light.

And thus as day faded into night we continued to work. There were some communication issues that were still working on, but Warren was able to align PIAA. We were also able to get on sky later in the evening. The image below is an image of our first target of the run Theta 1 Orionis B.

So with a long 12 hour work day which continued into the night we were reminded of the song “Don’t Stop Believing” by Journey. As even though the team was presented with different challenges through the day; we never stopped believing.
