GCN Circular 27128
S. Belkin (IKI), A. Pozanenko (IKI), E. Klunko (ISTP), E. Mazaeva (IKI), A. Volnova (IKI) 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. 18 (UT) 16:02:31. We did 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). Upper limit is 22.8R. We detected the object reported earlier (Pozanenko et al., GCN 27122) with coordinates (J2000) 10:41:44.54 +19:28:19.3 which is 14.5 arcsec apart from center of enhanced XRT error circle (Goad et al., GCN 27106). Preliminary photometry of the object is following: Date UT start t-T0 Filter Exp. OT Err. UL(3sigma) (mid, days) (s) 2020-02-18 16:02:31 2.12497 R 30*120 22.7 0.3 22.8 Power law index of a light curve of the object calculated between the two epochs is about -0.3. Therefore the object might not be related to GRB 200216B.
