TITLE: GCN CIRCULAR NUMBER: 23920 SUBJECT: GRB 190219A: CrAO and AbAO optical upper limit DATE: 19/02/21 18:44:49 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Volnova (IKI), S. Nazarov (CrAO), S. Schmalz (KIAM), R. Ya. Inasaridze (AbAO), A. Pozanenko (IKI), S. Belkin (IKI), E. Mazaeva (IKI), I. Molotov (KIAM) report on behalf of IKI-GRB-FuN collaboration: We observed the field of GRB 190219A (Beardmore et al., GCN 23902) with AZT-8 of CrAO, AS-32 (0.7m) telescope of Abastumani Observatory and ORI-22 telescope of ISON-Castelgrande Observatory, first observation starting on Feb. 19 (UT) 19:48:14. We do not detect any object within enhanced XRT error circle (Beardmore et al., GCN 23907). In particular we do not detect the afterglow candidate (Xu et al., GCN 23911). Preliminary photometry of the field is following. date UT start t-T0 Filter Exp. UL Obs./Tel.
