70-508 2026-04-07 00:19 SoftToO Sar2888 ALJd070121 - ALJd070129 Observed successfully with hitandrun with clear sky and seeing around 1.5" Observed
70-508 2026-04-10 01:08 ToO 6D93921 ALJd100055 - ALJd100068 Observed with clear skies. No seeing estimate. The target is very faint and thus not visible in the individual images. Calibration images were taken before and after the science exposure. Observed
70-508 2026-04-15 00:04 SoftToO 16cygb ALJd150144 - ALJd150147 Observed with clear skies. Observed
70-508 2026-06-17 00:48 ToO 2026MA ALJf170096 - ALJf170109 Observed with clear skies Observed
70-508 2026-06-19 01:08 ToO 2026MK ALJf190143 - ALJf190156 Observed before UT midnight with clear sky and seeing about 0.9'' Observed
70-508 2026-06-21 01:08 ToO 2026MF1 ALJf210076 - ALJf210089 Observed with clear sky and seeing about 0.5''. I noticed a squiggle in the star trails starting with ALJf210083.fits (though prior ones might have gone unnoticed), indicating minor issues with tracking. griz-calib-images were taken before and after the science exposure. Observed
70-508 2026-08-21 01:06 ToO SAR2901 ALJh210122 - ALJh210135 We initiated the script right before midnight, so we had to cancel it and we tried after midnight due to the nature of the asteph moving_target_script. Observed under clear skies and sub-arcsec seeing. Observed
70-508 2026-09-03 00:44 SoftToO 2026RB ALJi030096 - ALJi030109 Observed with clear skies and sub-arcsec seeing. Note that the target is seemingly located in the corner of the image. Check if data is useful. Observed
70-508 2026-09-11 00:50 SoftToO sar2901 ALJi110214 - ALJi110263 observed with clear skies and good seeing. observations were pushed back to end of night due to winds. Observed
70-508 2026-09-23 00:00 ToO sar2901 ALJi230094 - ALJi230102, ALJi230103 - ALJi230113 Attempted, but aborted due to unstable seeing. Observed
70-508 2026-09-24 00:03 ToO sar2901 ALJi240056 - ALJi240061 Observation attempted in shared risk testing of new OB generator. Testing worked fine. Seeing was too high for the trigger and the OB was interrupted. Observations failed. AAD. Failed
70-508 2026-09-29 00:37 ToO sar2901 ALJi290343 - ALJi290452 Shared risk observations of OB using new-generator compiled Staff script. AAD. Observed

 

The above information is collected from the ToO/Mon reports that have been created by the observer.

Should any of the observations have been carried out using the OB system, you will find additional information HERE
