The long duration GRB 181201A (Mereghetti et al., GCN 23469; Khanam et al. GCN 23501) field was observed on 2018-12-11 with the 2-m Himalayan Chandra Telescope (HCT) located at Indian Astronomical Observatory, Hanle, India. Several frames of 150 seconds in Bessell's R-band were obtained. The optical afterglow candidate (Gorbovsky et al., ATel #12255; Podesta et al., GCN 23470; Kong, GCN 23475; Lipunov et al., GCN 23476; Volnova et al., GCN 23477; Heintz et al., GCN 23478; Mazaeva et al., GCN 23479, Watson et al., GCN 23481; Belkin et al., GCN 23485; Bolmer and Schady, GCN 23486; Reva et al., 23507; Srivastava et al., GCN 23510; Belkin et al., GCN 23514; Mazaeva et al., GCN 23522, Belkin et al. GCN 23601) was detected in the co-added frame (total integration time 30 min). Preliminary magnitude of the OT, calibrated using J211710.81-123706.3 (SDSS-DR12_id) is 20.72 +- 0.22 mag (2018-12-11, 13:55:01 UT). This magnitude is not corrected for reddening in the GRB direction and possible host contamination.
