APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 01, 2026 (SJD 61193) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Mon 01 Jun 2026 61193 bright (8.4 h, w/ 1.3 h for 8 deg design) ---- Observing Summary ---- Lots of clouds throughout the night and a few sporadic raindrops, including virga and precip associated with the clouds. Sometimes the clouds were coming from opposite directions. There were one or two times when it looked as if a sucker hole would open sufficiently to try and open, but nothing materialized enough to safely open given the nearby radar returns at those times. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

There's a sucker hole opening up to the west, but it doesn't look like it will last because the next wave of clouds is already east of Las Cruces. So, not looking like we'll open soon still. I should also note the next wave of clouds also have radar returns. 07:05Z - Some raindrops are falling now. 10:31Z - Still too cloudy around. Called it a night. FPS powered-off. Positioners are home/folded.
