| 01/14/2020 | DYahalomi S Hyman | TRES | 0 | 12.5 | 12.5 | 0 | 0 | 0 | Projector arm got stuck during tres.calib.short. . I ran a killcom and then redo and it fixed it. Very cloudy night. Power went out at 6:40pm. UPS lasted for about an hour or two and then everything shut off. The generator didn't kick in until around 12am. Around 12:30am with Emilio's help we got most of the computers and systems running again.
The 60" is still not operational though. Cannot get the tdata folder to open correctly with the current date. When you ls in tdata in an xterm the folder appears to be empty. In iraf, when I enter "trsdate now", it returns errors stating that the "raw data directory tdata/tres/2020.0114 not found." Same thing when I try to cd into the directory in an xterm. Gider also not working -- it opens with a ./tresguide start command but in the xterm it prints "Initializing guider camera... server down: GUIDECAM" and in the Guidefui window a pop-up reads "detector server not connected". In the bench computer MyStep window there are a repeated string of READ wait! last out |Ffindhome| lastread |Initial|". Tried running a redo and this didn't fix it. In the tres.err window there are repeated prints of do_pulizzi waits on." We checked the box labeled Pulizzi above the bench computer. It is turned on, but there are several labels that have lights below them that are not on that maybe should be on. Didn't want to try pressing buttons without knowing what I was pressing.
Luckily, it was very cloudy for the essentially the entire evening. So I am not sure how much observing that we missed. I went over some basic training with Sley (as much as I could do without observing...)
