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:

We thank the observing staff at IAO and CREST for helping with the
observations.
