MDM Observatory 2.4m Telescope Observing Report for 2025 May 15 Observer(s): anderson Institution(s): MDM Instrument: Osmos Worked for 1 hours (all night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Clear, Winds Calm, dust Mid: Clear, Winds Calm, dust End: Clear, Winds Calm, dust Observing Summary: Closed basically all night for dust. Could not guide at all. I could see stars, but not find any that matched jskycalc (more info in email to eric and john). Not sure what the issue is I found a few issues with Sally's attempts mainly that the guide probe was not stepping correctly and needed to be reset and the focus was too high (this may be due to a restart of the TCS). I have struggled to find a guide star before but not on many targets like tonight. Not sure what is causing it. ------------------------------ Submitted on 2025 May 16 [4:27:20]
