GRB 230812B: Optical observaions from Rozhen Observatory
Abstract
We observed the field of GRB 230812B, detected by Fermi GBM team (GCN 34386; GCN 34387) with the 50/70 cm Schmidt telescope at Rozhen NAO, Bulgaria. The observations started at 19:43 UT of 2023-08-13, 24.75 hours after Fermi detection. We took 18 images with 180 sec in I-band. The stacked image was calibrated in Cousins I-band after transformation from the PS1 catalogue.The counterpart of GRB 230812B was detected with 19.82 +/- 0.15 mag at the position of RA and Dec as 36' 31.5" and 51' 31.81" respectively, which is within the uncertainty of the X-ray position (GCN 34400).
