              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
KOSMOS broke pretty hard following the observer trying to pause/abort an exposure. I had to do a full reset to get everything working again, including going upstairs to power-cycle the torrent fiber box. Troubleshooting ended up taking about 40 minutes. After getting back on target, the observer reported that their 300s on-sky exposure looked like a bias/dark. I tried moving the cal stage in and taking a quartz image, and it looked fine, so I'm not sure what happened to their science image. I don't think the cal stage was blocking light for the science image, because we could see the sky in the slitviewer. Nevertheless, it seemed to be fixed after my test quartz, and we didn't have any more issues.
No other problems tonight.
