TITLE: GCN CIRCULAR NUMBER: 12898 SUBJECT: GRB 120119A : LOAO Optical Observations DATE: 12/01/24 09:13:48 GMT FROM: Minsung Jang at Seoul National U M. Jang, M. Im (SNU), and Y. Urata (NCU) on behalf of EAFON We observed GRB 120119A (GCN 12859, Beardmore et al.) in B,V,R- bands with a 1 m telescope at Mt. Lemmon, Arizona, US. The observation began at 06:03:31 UT, ~ 2 hours after burst alert. We took 3 frames for each filter with the exposure time, 300 secs The afterglow candidate was detected in stacked images of all three filters with a preliminary magnitude R ~ 20.3 +/- 0.2 mag. The photometry calibration is based on two USNO B1.0 stars, USNO-B1.0 0809-0167573 and 0808-0168858 We thank the LOAO operator, J. Yoon for his help with the observation.
