We observed the localization region of Fermi GRB 230511D (trigger
705537623). We obtained a total of 75 images covering ztfg, ztfr bands for
a total of 8750 seconds. The observations covered 951.5 square degrees
beginning at 2023-05-12T04:02:10.000 (5 hours after the burst trigger time)
corresponding to ~60% of the probability enclosed in the localization
region. The median depth of the observations was ~21.3 mag. Our
observations cover the part of the localization that is northwards of -24
degrees declination. Any candidate-counterparts will be announced in
forthcoming GCNs.
