Equipment Failure
Blazar photo-z measurements. Technical issues: Had issues with tracking, and ultimately had to restart the software a few times to get things working. On one reset the node service wouldnt shutdown/startup properly but Paul and Brian helped resolve this. After that no other issues for the remainder of the night.

Never opened due to dust. NOT weather page never fell below 30, but there were several domes open throughout the night including NOT. The site map never showed NOT had dust warning, only GTC showed it. The mirror cover was showing as open when I logged on and not knowing if there's an issue there I left as is. I only took bias frames.

Too much dust in the air (24-38 micrograms per cubic meter) to open dome. Gave up an hour before sunrise.

We observed about 3.5 hours until the tracking start to fail. I did the full restart two times, but it is not fixed the problem.

WD photometry. After about 3h of observations, tracking started to fail, and became unbearable shortly after, lasting only a few minutes after RA/Dec resets, and same after full restarts.

Clouds
Asteroid photometry. Dust at 27-23 at start of night, stable most of evening; after I closed b/c of clouds, aerosols increased to 35 suddenly. Clouds interfered for at least half of my 4 hours. No tracking problems, but incomplete slew ("unable to complete slew...") message forced a full restart, and a re-setting my protocols. File space disappeared without warning, so all asteroid files and later darks were lost. Slewing was fine after restart.

Equipment Failure
At the beginning of the night telescope tracked for about 30 minutes without issue on a target while using autofocus and waiting for twilight to end. Within 10 minutes of starting guiding, tracking turned off. After full restart didn't use guiding and tracking only turned off two more times (both very close to airmass 2 in the west, though).

Equipment Failure
Asteroid photometry The first 3-4h were great, the telescope pointed and tracked fine, but then it stopped tracking. The usual reboot fixed that, but only for a short while.The period between the loss of tracking became shorter and shorter. After 5 reboots, it would not even track for a single exposure.
