TITLE: GCN CIRCULAR NUMBER: 23853 SUBJECT: GRB 190202A: R and I band observation from HCT DATE: 19/02/04 07:09:08 GMT FROM: Brajesh Kumar at Indian Inst. of Astrophysics Brajesh Kumar (IIA), Avinash Singh (IIA), Ashish Raj (IIA), S. B. Pandey (ARIES), D. K. Sahu (IIA) and G. C. Anupama (IIA) We observed the field of GRB 190202A (Lien et al., GCNC 23830) with the 2-m Himalayan Chandra Telescope (HCT) located at the Indian Astronomical Observatory, Hanle, India on 2019-02-02 (21:32:29 UT). Two frames in Bessell R and I-bands with an exposure time of 300 sec each were obtained. The OT candidate (Novichonok et al., GCNC 23831; Steeghs et al., GCNC 23833; Cucchiara, GCNC 23839; Paek et al., GCNC 23841; Malesani et al., GCNC 23842; Belkin et al., 23843; Moskvitin & Spiridonova, GCNC 23844) is clearly detected in both frames at the Swift UVOT coordinates (Kuin & Lien, GCNC 23834). The preliminary magnitudes calibrated against the USNO-B1.0 catalogue are following: UT-mid Band Mag ------------------- ------ -------------- 2019-02-02 21:34:59 R 20.66 +/- 0.17 2019-02-02 21:40:56 I 20.08 +/- 0.20 We thank the observing staff at IAO and CREST for helping with the observations.
