Eclipsing binaries and variable stars. Dome had trouble tracking tele; closed/reopened, homed, and finally worked. ACE crashed when trying the focus routine, required a simple restart of ACE. Lost an eclipse as tracking failed at HA +3:50:00, tele wouldn't move, kept saying equipment failure, so a full restart of tele/ccd software/nodes required; happened again middle of the night, same reason. Keyboard on CCD must've been set to Spanish layout, I couldn't type login/pw to my Box folder with browser b/c shift+2 would give " instead of @ etc...Maybe someone can set it back to US standard?

WDs. Tried autoguiding without success. Setting binning to 2, regions all to 1 and "auto ROI" worked for a few images, then the star moved out of the field. Making any change in the autoguiding setup typically involves a full reset. Without autoguiding I noticed some DEC sudden jumps (about 30 px) during the night, probably the reason of the failure above. Dome got stucked at az aprox. 330, and the end of the night the humidity was unstable.

High humidity and high wind delayed opening. Once both had dropped, I opened the dome, but never received a confirming "dome is open" signal-- it just kept showing "dome is opening." Same thing when I reversed this and tried to close the dome-- it just stayed on "dome is closing" without ever saying "dome is closed." I repeated this procedure several times, but with the same result each time. I don't think that the dome actually opened since when I tried to take an image it had no stars. Same thing later when I decided to give up and close down-- I got a perpetual "dome is closing" message. I took an image to verify that the dome was closed and it came out with no stars so it did seem to be closed.

Asteroid photometry and remote observing for class later. Never opened the dome. No connection issues to camera and telescope PC until I tried a full restart to solve the filter wheel access and locking. I was unable to restart the JKT Warm Room PDU . With recent snow and dome locked in position there may have been a power problem regarding the JKT Warm Room PDU access and filter wheel locking mechanism. (A quick restart didn't solve the problem, so I tried the full restart.) No observing possible until these problems are analyzed, fixed, and a clear go ahead is given. Brian was very helpful in explaining what may have happened.

Connection Issues
Standard star fields for calibration. The camera was not responsive when trying to take test images for evening flats. Had to restart and missed flats. Tried using the Guide camera, but it became unresponsive after the second star. Did not try to restart connection because did not want to waste more time. There appears to be aberration with the U filter. At first thought it may have been a tracking issue, but only seemed to affect U filter observations (perhaps a known problem), making the stars appear elongated, rather than the expected PSF. Used autofocus, and seemed to work pretty well.

Equipment Failure
WDs photometry. System quite unstable. Telescope was out of limits on arrival, Brian and Peter connected to solve the issue rapidly. After about 2 h of observations with autoguiding, the main CCD stopped taking images without any error or warning. Reseting the system solved it. Slewing to a different target kept the DEC drive moving past the object, and had to cancel the slew command manually and repeat the pointing to avoid going out of limits. After retrying with the autoguiding (after a full reset), it only lasted less than 1 h, so I stopped trying, and spent the rest of the night without it. Even so, the acquisition stopped a couple of times without warning again. Finally, when sending the telescope to its park possition, the slew was aborted (as usually happened before), but I could not find the "RA/DEC reset" switches that typically solve the issue even after clicking at the radio buttons at the "ACE connector client" menu window and went for a full reset instead.

Eclipsing binary star; Lost 2.5 hrs due to software issues. First one was around 1:30am where we noticed tracking had trouble and then the dome was said to be Ajar and vignetting the scope and slewing said it failed. We had to do a full reset. Then at about 4:25am the CCD software crashed and we thought we started it back up alright, but we lost our field, which at first we thought were clouds, but after 30 mins we moved to M42 and the sky was not behaving, so we went through many restarts and after a couple full resets we were able to observe, but lost 2 hrs. It seemed that the tele was not aligning with the dome's slit and we must have been observing the dome. At 6:15am the telescope was stuck in the west and couldn't be parked. A few resets later and using the paddle to move tele freed it up and we closed.

Tried to use the autoguider for the first time. The camera seemed to work as expected, but no corrections were being made to the telescope's pointing. I attempted to adjust exposure time, focus, parameters, etc, but nothing made a difference. There are a number of other issues which I hope will be worked out over time. The primary one is that the guider images display over the science camera image on DS9. And I did not see a good way to redisplay the science image in another frame (no access to the D: drive?). Near the end of the night the RA tracking stopped. The telescope would not move in RA. I could move the telescope in Dec using the hand paddle and it would move some distance in Dec when trying to slew before canceling the move, but would not move in RA. Regained motion control once but lost tracking again almost immediately. With only 45 minutes left in the night at that point, I restarted the entire system again and got motion control, so just moved to stow position and closed for the night.

Obsering blazars to calculate photometric redshifts. Multiple times throughout the night, the telescope lost tracking. Sometimes this happened 10 minutes into an exposure, sometimes 40 minutes in. When trying to fix this, the node service lagged shutting down for about 30 minutes but eventually fixed itself. This problem only occurred once during our 4 restarts.
