INAF queue observing, 2026 Apr 05 - Apr 06

Observers:
ISA: Justin Ruppert
Telescope Operator: Josh Williams
Instrument: PEPSI

Summary

These observations have been performed in service mode, due to the unavailability of the LBT-Italia observers. Clouds were a nuisance for a significant portion of the night. We start with LBC but no science data have been taken due to clouds, we reconfigure to PEPSI at 02:40UT. We take some data until 08:26UT, when we close due to clouds. Then, Josh calls the night due to clouds at 11:17UT.

Night duration (12 degree - twilight) 03:00 - 12:00 UT = 9h 00m
Observing time: 5hr 26min (60.4%)
Weather time loss: 3h 34min (39.6%)
Technical time loss: 0h 0mins (0%)*
Shark-VIS+NIR time loss: 0h 0min (0%)
