68-302 2024-04-14 00:15 ToO EP240414a ALHd140039 - ALHd140043 The data was shared with program 69-811. The data consists of 5 frames with r' filter that was in an OB of program 69-811. Observed
68-302 2024-04-15 00:37 ToO EP240414a ALHd150066 - ALHd150078 During the observations, seeing started at 1.9'' and improved to 1.5''. The r' band observations showed some visual signal near the two stars of the source, but yesterday it was stronger. In summary, observed filling the requirements. The data was shared with program 69-811, so the marked time spent is only half the observation's duration. Observed
68-302 2024-04-18 00:22 ToO EP240414a ALHd180212-ALHd180215 ; ALHd180228 - ALHd180232 Observed through thin clouds and seeing of around 1 arcsec. On the first attempt at 01:01 UT, we only took the first two filters because the clouds became very thick afterwards. We observed files ALHd180212-ALHd180215, from 01:01 to 01:19. On the second attempt at 2:18 U.T. when clouds were finally looking thinner, we tried again, and observed only the i-band and z-band. This produced files ALHd180228 - ALHd180232. The g-band was observed correctly on the first attempt on files ALHd180212-ALHd180213. Observed
68-302 2024-04-19 00:13 ToO EP240414a ALHd190189 - ALHd190198 Observed with thin clouds and variable seeing. Observed
68-302 2024-04-20 00:24 ToO EP240414a, EP240420a ALHd200058 - ALHd200066, ALHd200104 - ALHd200108 EP240414a: Observed with clear skies and 1.3-1.6'' seeing. Although observations were attempted at the maximum distance possible from the moon, several of the exposures seem to be near the limit of sky-level saturation. Data shared with program 69-811 EP240420a: Data shared by program 69-811. Observed with clear skies and subarc seeing. Target had to be observed close to the moon, but on first glance, the sky didn't seem to saturate. Observed
68-302 2024-04-23 01:12 ToO EP240414a NCHd230204 - NCHd230275 Observed with thin clouds and seeing around 1 arcsec. Some data affected by passing clouds. Observed
68-302 2024-04-25 00:48 ToO EP240414a NCHd250306 - NCHd250341 Thin clouds and a seeing of between 0.7 and 0.9 arcsec. Observed
68-302 2024-04-29 01:00 ToO EP240414a ALHd290182 - ALHd290193 Observed
68-302 2024-05-06 00:00 ToO -- -- Target not observed due to technical issues with ALFOSC. Failed
