Problems:
1. Lost guiding: when the exposure of the image frame #964999 was started, the guider stars were all set, but after almost half of the exposure was done, there was an error message in the guider status. We stopped the exposure and read out the frame early. Later we went back to this position to check how many guide stars are available and confirned three bright stars.
2. Minor display glitch on Observer Console: We noticed that the exposure status bar in blue got stuck at ~65% position until the exposure was finished. Reloading the page didn't work but the time left in the exposure was displayed correctly.

Another great night with a clear sky and low wind. Seeing started around 0.85" and got improved after midnight down to 0.7". We had to discard one exposure due to the guiding problem. Other than that, it was a very smooth and productive night. We started the first exposure of the ToO observation at 5:48am in local time (08:48UT) and finished at 6:06am (9:05UT).
