TITLE: GCN CIRCULAR NUMBER: 29205 SUBJECT: GRB 201229A: AbAO optical afterglow detection, TSHAO optical upper limit DATE: 20/12/30 11:31:43 GMT FROM: Alexei Pozanenko at IKI, Moscow N. Pankov (IKI, HSE), A. Pozanenko (IKI), R. Ya. Inasaridze (AbAO), I. Reva (FAI), V. R. Ayvazian (AbAO), G. V. Kapanadze (AbAO), S. Belkin (IKI) report on behalf of IKI-GRB-FuN: We observed the field of GRB 201229A (Sbarufatti et al., GCN 29192) with AS-32 telescope of Abastumani observatory (AbAO), and Zeiss-1000 telescope of TSHAO in R-filter. We detected the optical object at the edge of enhanced XRT position (Osborne et al., GCN 29193). An optical afterglow candidate (Sbarufatti et al., GCN 29192; Moskvitin at al., GCN 29204) is detected in AbAO observations and not detected in TSHAO observations with shallow upper limit. Coordinates of the optical object (J2000) 14:02:45.36 +48:11:53.5 with uncertainty of 0.3 arcsec (in both coordinates) are consistent with coordinates reported by UVOT (Sbarufatti et al., GCN 29192) and SAO RAS (Moskvitin at al., GCN 29204). Preliminary photometry of the object is following Date UT start t-T0 Filter Exp. OT Err. UL(3sigma) (mid, days) (s) 2020-12-29 20:38:18 0.42095 R 23*120 n/d n/d 20.2 Zeiss-1000 2020-12-30 01:52:12 0.64354 R 68*60 21.1 0.2 21.3 AS-32 The photometry is based on SDSS DR12 star (Lupton transformations) RA DEC R(Lupton) 210.720000 48.157954 18.28 The non-detection of the object by Zeiss-1000 is consistent with Nanshan/NEXT optical upper limit (Fu et al., GCN 29203). The object is absent in SDSS DR12 and we confirm the afterglow of GRB 201229A.
