70-301 2025-02-03 01:13 ToO EP250108a ALIb030155 - ALIb030170 First frame of OB did not meet seeing requirements, however after contacting PI it was acceptable to increase seeing limits. Continued observations with variable seeing between 1.8" - 0.9". First g-band frame was taken at a lower airmass than the rest of the frames. Observed
70-301 2025-02-05 00:24 ToO EP250205a ALIb050093 - ALIb050097 ToO was observed according to requirements. Seeing was 1.5". Strong winds in the first half of the night forced this to be observed in the second half only. Observed

70-301 2025-02-12 00:26 ToO EP250212a NCIb120070 - NCIb120087 Observed with seeing 1.0. Target could not be located Observed
70-301 2025-02-14 00:00 ToO EP250108a ALIb140207 - ALIb140217 Set as failed. Thick layers of clouds arrived shortly after the beginning of exposures. The first few images are available in case they are usable. Failed
70-301 2025-02-16 01:06 ToO EP250108a ALIb160040 - ALIb160057 Target observed with clear skies and seeing around 1.0". Observed
70-301 2025-02-20 00:00 ToO EP250220a ALIb200070 - ALIb200078 Clear sky seeing ~0.7 arcsec The "Time Spent" was moved under 70-805 TP Observed
