TITLE: GCN CIRCULAR NUMBER: 27122 SUBJECT: GRB 200216B: Mondy and AbAO optical upper limits DATE: 20/02/18 16:01:19 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Pozanenko (IKI), S. Belkin (IKI), E. Klunko (ISTP), R. Ya. Inasaridze (AbAO), E. Mazaeva (IKI), A. Volnova (IKI), I. Molotov (KIAM) report on behalf of IKI-GRB-FuN: We observed the field of GRB 200216B (D'Avanzo et al. GCN 27102; Fermi GBM team, GCN 27101) with AZT-33IK telescope of Sayan observatory (Mondy) starting on Feb. 16 (UT) 13:47:34 i.e. 15 minutes after GRB trigger. We also observed the GRB 200216B with AS-32 (0.7m) telescope of Abastumani Observatory starting on Feb. 16 (UT) 20:00:20. We do not detect any object in the enhanced Swift-XRT position (Goad et al. GCN 27106). In particular we do not detect possible IR-counterpart (Levan et al., GCN 27114). Preliminary photometry of the field is following. Date UT start t-T0 Filter Exp. OT UL(3sigma) (mid, days) (s) 2020-02-16 13:47:34 0.06915 R 30*60 n/d 22.0 2020-02-16 20:00:20 0.29256 R 67*60 n/d 21.8 Photometry is based on the USNO-B2.0 nearby stars. We note the presense the optical object at coordinates (J2000) 10:41:44.54 +19:28:19.3 and brightess of R=21.75 +/- 0.25 at 0.06915 days (mid time) after triger, and do not detect the object in the secod epoch R > 21.8 at 0.29256 days. The object is absent in both SDSS ans Pan-SARRS catalogues. The object is apart 14.5 arcsec from center of enhanced XRT erro circle (Goad et al. GCN 27106) and the object lies within 90% BAT ground-calculated position (Krimm et al., GCN 27117).
