58-502 2019-04-28 00:17 ToO grb190427a ALCd280152 - ALCd280154 Observed in clear skies with seeing around 1.0 Observed
58-502 2019-05-11 00:16 ToO grb190511a ALCe110064 - ALCe110066 Started exposing a few minutes before beginning of the nautical twilight. Moon distance 40deg, very thin cloud layer. Observed
58-502 2019-05-12 00:24 ToO grb190511a ALCe120053 - ALCe120056 Started exposing 5min before nautical twilight, thin clouds on the line of sight during the first exposure. There was no sign of the target in the first so exptime was extended for the last two exposures. Moon distance 44deg and seeing 1\". Observed
58-502 2019-05-30 00:37 ToO grb190530a,SP0946+139 ALCe300065 - ALCe300081 The GRB was observed in clear skies with a seeing around 1.5-2 SP0946+139 was observed instead of SP0946+139 due to airmass considerations. Observed
58-502 2019-06-13 00:38 ToO grb130613b STCf130009 - STCf130018 0.8 seeing. Thin clouds and dusty. Files STCf130011, STCf130012 not useful so replacements were taken. Observed
58-502 2019-06-28 00:37 ToO grb190627a STCf280021 - STCf280026 Observed
58-502 2019-07-19 00:37 ToO grb190719a ALCg190072 - ALCg190079 Observed in clear skies with seeing around 0.8. Observed
58-502 2019-07-20 00:53 ToO grb190719a ALCg200084 - ALCg200088 Observed in clear skies with seeing around 1.5 Observed
58-502 2019-07-24 00:29 ToO grb190719a ALCg240156 - ALCg240160 Observed
58-502 2019-08-29 01:50 ToO GRB190829A, Feige110 ALCh290078 - ALCh290108, ALCh290140 - ALCh290145 Started observing immediately after it was considered to be reasonable. Afterglow was clearly visible in the first exposure and scripts were adjusted according to the wishes on the fly. Seeing was good despite the low altitude. u, g, r, i, z imaging was done with manually edited script. Hopefully, all keywords are correct and the files are available in the correct locations. Observed
58-502 2019-08-30 00:54 ToO GRB190829A ALCh300143 - ALCh300161 Observed at a higher airmass than first requested due to a fixed program in the last 4 hours that could not be overridden. AAD. Observed
58-502 2019-09-05 00:29 ToO GRB190828B ALCi050099 - ALCi050103 The target GRB190828B succeeded. The target GRB190829A failed to meet the requirements after a few minutes into the script. Two frames was acquired and may be used, however, over the OB failed and therefore the marking. Observed
58-502 2019-09-06 00:45 ToO GRB190829A ALCi060182 - ALCi060193 Target observed in clear skies and good seeing. Observed
58-502 2019-09-09 00:56 ToO GRB190829A ALCi090046- ALCi090057 clear sky, seeing between 0.9-1.3 arcsec. Observed
58-502 2019-09-16 00:34 ToO GRB190829A ALCi160230 - ALCi160244 Notice 3 i_SDSS exposures could not be finished due to a thick cloud layer. Observed
58-502 2019-09-17 00:29 ToO GRB190829A ALCi170145 - ALCi170153 Thin clouds and observed with the moon. Seeing<1.0\" Observed
58-502 2019-09-25 00:33 ToO GRB190829A ALCi250138 - ALCi250147 Seeing <0.7\". Clear sky. Observed
58-502 2019-09-26 01:27 ToO GRB190926A ALCi260031 - ALCi260044 Observed with seeing 1.2-1.4\". It was not possible identify the target in the raw frames. Observed
58-502 2019-09-30 00:43 ToO GRB190829A ALCi300079 - ALCi300087 Observed
