MDM Observatory 1.3m Telescope Observing Report for 2025 Sep 02 Observer(s): Thorstensen (for Cohn) Institution(s): Dartmouth Instrument: Templeton direct Worked for 3 hours (last half of the night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Clouds all night. Beg: Overcast, Winds Light & Variable Mid: Overcast, Winds Light & Variable End: Seeing 1.5 arcsec, Cirrus, Winds Light & Variable Observing Summary: Classic monsoon in afternoon and evening, but cleared off well enough to open by about 2 AM (and the humidity dropped). There was high cloud, but mostly pretty light. Kitt Peak stayed closed. ostensibly due to high humidity, but it was about 50% at MDM so that seems a rather steep gradient. ------------------------------ Submitted on 2025 Sep 3 [6:17:05]
