Daily Reports
October 2, (Tuesday)
Andrew, Isabella, Jack, Laurent, Stefano, Matthieu and Bilal arrived at the telescope.
After a quick tutorial and a rough start, we manage to check pointing and focus on 2251+158. While it's bad, it's improving a lot with the night coming, and the weather is very promising.
We continue with a night of calibration measures, with beammaps on Uranus, Neptune, skydips and maps on the secondary calibrators, before we start with science projects.
[Andrew, Isabella and Jack took the shift Tuesday 10pm to Wednesday 6am.]
We started the shift with beam maps on Uranus and Neptune, followed by the @otf_loop_8_5 on each, before moving to NGC7027, CRL2688 and MWC349 for the otf loops.
After this, tau conditions appeared to be somewhat stable at tau~0.3, so we began science observations with the SZ LP 199-16, obtaining the 4 repetitions requested in the readme on PSZ2-G111.6. Up to this point, there had been some spikes in the tau, which was steadily trending upwards past 0.35. Next, after remaking the pointing and focus, we changed to project 094-18, and tried to make some maps of XLSSC102. The weather was becoming unstable, and trending about of 0.4, and we cancelled the observing script after 3/6 scans when it became clear that the conditions were no longer suitable for observing.
October 3, (Wednesday)
[Andrew, Isabella and Jack took the shift Wednesday 10pm to Thursday 6am.]
As the shift begins, the opacity is ~0.4, with a downward trend and appears to be becoming more stable. We begin with a skydip, followed by beammaps and @otf_loop_8_5 on Neptune, then Uranus. As with the previous night, this was followed by a pointing and OTF loop on each of NGC7027, CRL2688 and MWC349.
At midnight UTC (2am local) after pointing and focus on 2251+158, we begin the first science observations of the day for project 199-16 . Although we completed 4/4 repetitions requested last night, we go back for another 2 since tau was higher than requested yesterday. This time the conditions are very similar, with tau of ~0.35, but appears to be stable as we take the 2 repetitions on PSZ2-G111.6.
