TITLE: GCN CIRCULAR NUMBER: 22448 SUBJECT: GRB 180224A: AbAO optical observations DATE: 18/02/25 20:06:13 GMT FROM: Alexei Pozanenko at IKI, Moscow E. Mazaeva (IKI), A. Pozanenko (IKI), A. Volnova (IKI), R. Inasaridze (AbAO), V. Ayvazian (AbAO), O. Kvaratskhelia (AbAO), G. Inasaridze (AbAO), I. Molotov (KIAM), report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 180224A (Lien et al., GCN 22442) with AS-32 (0.7m) telescope of Abastumani Observatory starting on Feb. 25 (UT) 01:07:37. The afterglow of GRB 180224A (Lien et al., GCN 22442; Vladimirov et al., GCN 22444) is clearly detected in a stacked image. Preliminary photometry is following. Date UT start t-T0 Filter Exp. OT Err.
