Subject: 2.5m obslog 20211003 (SJD 59491) From: doravetz@apo.nmsu.edu Date: Mon, 4 Oct 2021 11:47:29 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 03, 2021 (SJD 59491) ---- Observing Team ---- Dylan Gatlin Dan Oravetz (R) Kaike Pan (afternoon checkout help with TPM) ---- Observing Plan ---- focus v altitude tests ---- Observing Summary ---- The first part of the night we stayed closed and monitored the clouds and high humidity. Around midnight the clouds cleared and the seeing started improving. We opened at 07:30Z to clear skies and seeing better than 1" fwhm and started collecting focus-versus-altitude data (see Log for focus sweeps). Notes: - Towards the end of the night the ALT axis exhibited an oscillatory behavior between positions 65:20 and 65:18. After looking at the drive surfaces it may have been a result of moth remains. Day staff, could you please check and clean the ALT surfaces? - When the ecamera is turned off, the ecameraICC stays alive. However, when the ecamera is turned back on, the ecameraICC crashes and needs to be restarted. - sop gotoStow doesn't work when at 5deg, so you need to use the Go To 5 script to go back up ---- Observing Log ---- Afternoon ========= APOGEE cals started, including 30-read FPI The ecameraICC needed to be restarted when the engineering camera was turned on Mirror numbers in spec Counterweight 2 is reading as 210 in the MCP, but it is actually at 410 like the rest. To fix this, I decided to try to restart the MCP. This didn't fix the issue. I tried restarting the TPM, and when starting it back up, the Terminal kept printing the warning FIXME reply cw multi OK comm unknown TPM_MULTI This happens when you have the wrong version of the TPM loaded. When resarting with a `module load tpm/git`, the error went away and the TPM worked. We updated the confluence instructions. Even when loading the git version, the TPM gui shows a version 1.0-11, which is very old and probably not the actual running version. 23:50Z began ventilation Night ===== Didn't open at sunset due to approaching clouds and we wanted to watch the humidity trend at sunset as the temperature dropped. Partly cloudy. Humidity increasing. 03:43Z - Stopped ventilation due to increasing humidity (~80% and climbing). Still have clouds moving through. 06:00Z - Started ventilation again. The sky is clear at the moment. The 3.5m reports best seeing is 1.3" fwhm. We'll monitor to see if it gets a little better to be within the necessary constraints for the altitude-vs-focus test. 07:30Z - 3.5m reports improved seeing <1" fwhm. Opened. 07:43:39 tcc track/pterr 0, 65 obs /rotty=obj /rota=0 /magRange=(11, 12) 07:57Z - We performed several focus sweeps. The best focus has fwhm of 0.8 to 0.9 arcsec, but the actual focus at which the best focus occurs changes by as much as 50 um. M2 is currently about 2C cooler than ambient temp. AZ=-5, ALT=63, ROT=176, best foc was at -100um in the first sweep, then -55um in the next. After a series of focus sweeps over the course of an hour, we were ready to begin the test and the focus has stabilized at -100 All focus sweeps are done with center -100, 7 steps of 15, 10s
