Imaged pulsating white dwarf EC14012. Had some issues with VNC Viewer towards the end of the night, kept freezing to the point where I had to restart my computer and re-log into the VPN for it to connect again. Called the night shortly after that as it started to make us nervous.

Equipment Failure
Several positive fixes for the telescope weren't enough. The same non-connection exists and may be the reason that sidereal time ran backward. Using the Andor camera from the Camera telescope does not afford the choices in saving your images or setting up a proper script. I was able to open and close dome, mirror covers, and use dome automation, but did not progress to tracking an object. Sara Observatory computer and its cameras were useful.

Software/Control PC Issues
CCD can be operated from the camera window on the connector-client pane from the CCD computer, but trying to connect the OBSERVATIONS panel from the ACE control system on the telescope computer always waits a bit and says "could not connect to the camera. Please check that the camera computer is powered on and the ACE Node Service is running". This persists across restarts of the node service, connector client and ACE control. I got as far as finding a focus, then figured out why I could not identify any fields. The indicated UT, LST and RA all jump backwards (by up to 2 hours) every minute or two while the telescope is either stationary or tracking. It insists that it's December 30, 2023. Dome is closed, drive off, telescope parked at what may or may not be the meridian at +20.

CCD temperature was cycling between -10 and -50 C, while telescope computer froze repeatedly. Brian Brondel checked in did some diagnostics and power cycling, with no joy. The last straw was the readout freezing while trying to do a series of darks to see whether the temperature was really doing that or it was a sensor issue.

we looked at pulsating helium atmosphere white dwarf EGGR 63. realized our problem the last two nights was trying to slew from the H.A. tab instead of the R.A. tab. we are always learning! VNC had some connection issues again but it is hard to say if that's due to our less-than-ideal internet, the VPN connection, or something else.

AGN hosts, H II regions. Focus 128000. Once while tweaking focus, a message box popped up about initializing a controller (I didn't get its number, but the spectrograph was not selected before or after). Clicking on that, the auxiliary instruments, focus, and observations panels were whited out for a few minutes, then the drive and auto dome had turned off .Tracking does get more irregular in both axes west of about 1h45m west. A few exposures looked as if they had crosstalk during readout only for part of the chip roughly y<750.

Asteroid light curve. New equipment just installed and I was unable to have a complete readout and reset without the message "Exposure start failed." Next exposure prevented, countdown of remaining seconds not running. Closing and Opening the Operating menu id not solve the problem. Also, was unable to save images and unclear about latest image storage drive (D, Z, or "image storage (\\ISP address)). No files showed up, binning uncertain. Cause could lie in guider menu or connection of other CCD on menu. Seemed that de-interlace choice changed. Peter left message for help to which I replied. Closed down, never opened.

Observations went smooth for the imaging of star HD45698 (a field roAp), I hit abort on accident in the beginning so had to cycle everything, besides that nothing to complain about! Got 1300 exposures, 20 seconds each, at a median of 1.2 Mil counts for Intensity and 20k for Source. No cloud coverage with an average humidity of 40% and 1 mph winds! Beautiful night.

Connection Client not working on SARA CAM. Without this, time of exposure start is not written to FITS header, so I can't use the data for time series. I will email sara-tech to see if anybody needs imaging data and doesn't care about time precision.

Software/Control PC Issues
Time series photometry of intermediate polars. First time on CTIO in a long time. Got things going with a little help from Brian and Kurtis and Todd. DS9 was not displaying images, but I managed. At about 06:00 UT I realized that the exposure start time was not being written to FITS headers, so data are basically useless. The Connector Client is not working on Camera computer. It will not start - crashes every time. I restarted the computer and that did not help. I did a reboot from the PDU, and that did not help. Tried again, and now I can't even get SARACAM back in VNC. So I'm shutting down for the night. It was a beautiful night with reported sub-arcsecond seeing. It would be helpful to have instructions on how to get things going again on the desktop or website. Nowhere could I find the instructions for how to restart everything from scratch. Such a document would be useful to have on the desktop. Why is "other observers" a required field of this form? (yes, I'm grumpy).

Galaxies, Didymos dust trails. Focus 126300. At one point telescope control system crashed but left a frozen window, confusing me mightily until I sent CTL-ALT-DEL from VNC and made everything refresh. At one point near 4h W -77, guider could not keep up with NS daifts (or didn't have the control authority against backlash to do so?)

rOAp stars. At the beggining of the night, I could not connect to Telescope computer. I power-cycled it. And it is now working and I can access the TCS. I cannot connect to the Andor camera. I to connect to the guider camera. This failed. I then tried stopping and starting the camera ACE node service. Didn’t fix the connection to the camera. I then tried closing and reselecting the main camera service. The ACE connector client failed. This likely indicates that it cannot connect to the camera. This probably requires a restart of the camera and a full ACE services restart. The failed guide cam together with this failure suggests something systemic is wrong. I power-cycled the camera. This did not restore the connection to the ACE connector client. I then tried to power-cycle the camera computer because the broken ACE connector client remained that way, even after stopping and starting the ACE node service. It appears that the camera computer would not reboot completely as I cannot connect to it.
