70-501 2026-10-02 00:07 SoftToO 2026acxa, ZTF26abxkuhv ALJj020064 - ALJj020068 OK shared Observed
70-501 2026-10-03 00:26 SoftToO ZTF26abwrwdz ALJj030155 - ALJj030161 2021aeuk missed due to overscheduling of monitors during the first half of the night. ZTF26abwrwdz observed under thin clouds and seeing around 1.5" Observed
70-501 2026-10-06 00:26 SoftToO ztf26abzfswo ALJj060279 - ALJj060285 observed under clear sky seeing was ~0.8". Observed
70-501 2026-10-07 00:00 SoftToO Failed
70-501 2026-10-10 00:35 SoftToO ZTF26abymijj ALJj100239 - ALJj100245 Observed successfully with clear skies and sub-arcsec seeing. Observed
70-501 2026-10-16 00:27 SoftToO ZTF26acaahql ALJj160123 - ALJj160128 Observed under clear skies. With seeing ~0.7". Observed
70-501 2026-10-26 00:00 SoftToO Targets missed due to bad weather conditions - high humidity and thick clouds. Failed
70-501 2026-10-30 00:40 SoftToO ZTF26acbujyo, ZTF26abfmmvq ALJj300198 - ALJj300204, ALJj300205 - ALJj300211 Observed partially with thin clouds and seeing of around 0.7". Because of the varying cloud coverage, target (ztf26acbujyo) was lost during second half of the exposure, i.e. second half of the exposure is unusable. Check if data is still useful. ztf26abfmmvq observed through thin clouds and seeing of 0.8". Observed
70-501 2026-11-04 00:29 SoftToO ZTF26accxaig ALJk040119 - ALJk040125 Observation started under thin clouds, undef DIMM seeing. Ended with very hazy cloud cover, therefore early readout initiated. Failed
70-501 2026-11-06 01:22 SoftToO ZTF26abzlqjb, ZTF26accxaig, ZTF26aamqluf ALJk060059 - ALJk060062, ALJk060064 - ALJk060078 ZTF26abzlqjb attempted, failed because of closure forced by high humidity. ZTF26accxaig, ZTF26aamqluf observed under clear skies and seeing around 3". Observed
