Tested the spectrograph, noted that the instructions show a figure of the FLI CCD at 10 deg C and large dark current obscurred long exposures of faint spectra, so set to -40 and seemed to fix. Initially moving the telescope required it to be sent to the target twice before it would move. EB program for eclipse timings and light curves with spectra for velocities and detecting certain elements.

Microvariables. Two hours from sunrise the camera client failed. The camera did not download. I closed and restarted the camera client. I was able to take a series of images without incident. Then the temperature readout flipped to -1000. The camera was still reading out and the background appeared normal so the camera had not warmed up. Then the filter wheel #1 started moving on its own. I reinitialized #1 wheel and it worked for a few minutes. Then the ACE client failed and the dome control failed. I closed and restarted the ACE telescope control and everything worked again. I also closed and restarted the Leach Camera client on the camera computer. The dome interface reported that it was ajar though I had not tried to close it. I then closed the dome and it appeared to work correctly. All the clients are functioning again.

Logged on this morning to check the status of the telescope-- no one was using it so I logged on for a couple of morning targets-- first set of images were fine, but when I moved to the second target they came out looking like biases.

On a previous night I took long/short flats and attempted to make a bad pixel map since there are a couple columns that appear bad, but they didn't come out in my maps, so maybe someone else could try and share? I have stellar comps that run into them over the course of the night as things meander.

1. We think the relative humidity indicator is about 10%-15% higher than the actual value. The website from the National Weather Service, linked below, gave a humidity that reflected off what was seen through the all-sky cam and the data being collected. Being able to clearly see the Milky Way through the cam. 2. The current dew point/wind data display has not been functional since 2020. 3. The 2.1 meter dew point/wind data display stopped functioning the 17th of November, this month. 4. The Dropbox directories are nearly full, needing to be emptied. The limited the space we had available.

Software/Control PC Issues
Had an issue with the VNC connection on the Camera computer. Worked initially, but after observing for a few hours, it through a connection related error seemingly. Closed VNC viewer on our end and restarted our computer several times too, but neither fixed the issue. Seems that the Camera computer is somehow still connected or at least trying to connect to that initial VNC instance, which is preventing the ability to reconnect to it. Also ended up having to restart the ACE window on the telescope computer, but we were able to get that back and working. Had no trouble parking the telescope and closing the dome.

We did not open the dome; only displayed ACE control system and camera system to visitors during our general open house. For some reason, the ACE control system and the camera window could not be put on separate screens. We had to toggle between them. Likely this is a local IT issue, but worth noting in case other observers experience the same inconvenience. The night was handed over to ASC observers around 11pm EDT.

Giant AGN-ionized clouds (probably observed mostly out of sheer obstinacy). ARC camera shutter still out, so I used a sequence of bias-obect-3 biases (i.e. zero exposure) to cleanse the chip and subtract the pattern from light reaching the chip during exposure. Furthermore, unless the guide star was really bright, the guider would only work for short periods before the star jumped away, and had "star faded" roughly every other exposure. The guider x-stage is not moving (and even after it thought it was running off to initialize was still in the same place). Images on the guider are pretty poor; it may be way off the edge of the field. Telescope focus jumped from 8500 to 62500 while I watched the readout change.

Doing twilight flats, V exposure showed blank at level 140, aborted. Then "exposure start failed", so I cycled the telescope-outlet power and rebooted both computers. Still managed to set on main target by the end of twilight. During 60m exposure, the QSI guider silently disconnected (while leaving the display looking plausible) so I got 30" diagonal trails. (No screaming so as not to disturb the cats.) The second 60m exposure was successful with a disconnection event just after its end. ARC camera froze again around 0030 MST. I was unable to get it to complete an exposure and read out after that, even after the restarts that worked before.

Observing Program - Monitoring Blazars: PKS 1156+295, and 3C 279. Problems: I couldn't figure out the syntax on how to automatically increment images number in the Leach software on the CCD computer. For the record the syntax is: imagename_{{seq:3}}.fts Turns out the .fts extension was the secret, thanks Brian and Bill. The images came down with 1.4 (lower right hand quadrant missing). I fixed it by going into "full frame" and changing the "readout mode" to amplifier A instead of "quad readout", They seemed to come down complete and normal. Brian said he would look at it this morning.
