MagAO-Classic has landed in TUS. This is the last MagAO-C 2019B post.
And I am currently surrounded by cats, who are much better snugglers than vizcachas.
Spot the vizcacha.
On the day we left I checked that everything was safely stowed.
Amali said goodbye to her rock garden.
We headed down the hill at 8:30am Chile time and got home to Tucson around 11am MST for a total of about 31 hours travel time.
The flowers were blooming at El Pino and the new dorms for our mid-day rest were really very lovely and extremely comfortable:
We saw Tyson in LSC and heard he had a nice stay at Hotel Enjoy. He was on the same SCL-DFW flight and was nice enough to get me into the club in SCL and Laird in DFW. It was nice seeing you Tyson, hope you made it home safely too!
Overall this was a good run, I think Emily did a great job learning MagAO and Amali did great working with her and refreshing her memory on the LBTI compare/contrast differences.
The song of the day: Taylor Swift’s Perfect Fight Song by Andy Wu Musicland featuring Pink, Ellie Goulding, and Rachel Platten:
Last night went great. Now today MagAO-Classic has been removed from Clay to the Aux and the clean room. Night schedules are switching to day schedules. It was a 3-viscacha day at the clean room and many NSF proposals have been worked on, and SPIE abstracts have been drafted and submitted to the extend possible.
Now it’s time for more proposaling and some packing too, so I leave you with the MagAO-Classic song of the day: Ylvis – The Fox (What Does The Fox Say?)
Tonight was our last night on-sky with MagAO-Classic in 2019B. It was my telescope night, and Amali ran AO after Emily went to bed around midnight. Tomorrow’s the big day for removing MagAO-C from the telescope, so we always do these staggered bedtimes. It’s nice to have Amali and Emily here to help with removal.
Alberto stayed an extra night with the rest of his turno, so this is the first time we’ve had him as our TO for the entire run. Thanks Alberto, you are a superlative telescope operator! Here are Alberto, Amali, and myself enjoying a quiet night of photon-gathering.
Amali’s blog post about the saga of the Alpaca was another creative expository piece that tonight we had a ceremony to award her the 2019B MagAO-C blog award:
Tomorrow there will be a general strike throughout much of Chile. The turno (shift changeover) that was supposed to happen will be postponed until Wednesday. That means those who hoped to go home tomorrow must stay 1 more day. We wish our colleagues all the best — they are all extremely professional and we truly appreciate working with them here.
The song of the day is Michael Franti & Spearhead – Say Hey I Love You — a classic from MagAO 2015B:
Tonight was Alycia’s first night. I told Emily it would be more relaxed than last night with all Jayne’s weird rotations because Alycia’s observations are more in MagAO’s wheelhouse — Alycia is searching for faint companions; keeping the rotator off for ADI mode; and is a Clio and general observational expert. But… hah.
So on the first Pre-set of the night, the Bayside-X stage decided to not work. There are 3 “Bayside” stages — they are the motors that move the AO system around so that the star is always on the tip of the pyramid WFS even when the star needs to be nodded around the detector on Clio for sky subtraction. We have replaced the X and Y stages with higher-power versions after we had observers who wanted to keep the rotator on and tracking, which caused the stages to overheat and fail. So I wonder if it’s a coincidence that we spent all last night with the rotator on, putting weight on the X-stage, and then tonight the X-stage refused to move…
Laird and Jared are now on pseudo-day schedules (see Alex’s great MagAO-X post about the unpacking today!) but this happened at the start of the night so Laird was still at the summit and Jared was down in the clean room with MagAO-X but he came up to help post-mortem. Laird went out to the platform with a walkie-talkie and we did the usual dance of moving the motors from the control room and Laird telling us what he saw or heard in the Nas. The current would spike but the motor wouldn’t move. Small movements and homing didn’t work; eventually we power-cycled them and in the end the X-stage did start responding again.
But Laird heard a noise that made him think there was some friction affecting the motion of the X-stage. Since the stage worked normally after the power-cycle, we started thinking about all the work we have done on the Baysides over the years. Originally we used the setting “Control always active” as that would position them precisely to the micron. But this was thought to contribute to the over-heating problem when we had high currents at strange rotator angles with all the weight of the instrument on the Y-stage. So we swapped the original out for the higher-power version, but we also started applying the brakes and turning off the active control after each move (“Stage” check box). But now we are thinking… maybe the brakes themselves are starting to fail, and the friction was the X-stage rubbing along its own brake. So tonight, Amali went into the code and reverted the procedure for the X-stage to now enable “Control always active” rather than enabling “Stage” (applying the brakes) after each move. And all stages worked perfectly for the rest of the night.
After Jared and Laird went to bed, at one point our TO Alberto went down to get some coffee, and I snapped this pic of the all-women control room. What a big difference from when I was the “Only Girl In the World” at LCO!
Classic MagAO song from Day 40 of the super long cold winter run with so many technical problems and such long nights that I actually worked, really worked, 112 hours a week (trouble-shooting all afternoon, observing all night, and choosing each day either a shower or dinner): This Must Be the Place/ Naive Melody by the Talking Heads:
