TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2828 SUBJECT: GRB041015, optical observation in CrAO DATE: 04/10/22 11:30:46 GMT FROM: Vasilij Rumjantsev at CrAO V.Rumyantsev (CrAO), V.Biryukov (SAI, MSU), A.Pozanenko (IKI) report: We have observed the error box of GRB041015 (INTEGRAL trigger 2019) with 2.6m telescope of Crimean Astrophysical Observatory. Six R-band images with 120 sec exposure were taken between (UT) Oct.16 21:25 - 21:38 under moderate weather conditions. The observed fields was 2.4x1.6 arcminutes centered at the error box. The upper limit of combined image is R~22.0 mag. as estimated from several stars USNO-A2.0 catalog. Comparison with DSS2 red plate does not reveal any new objects brighter than ~20 mag.
