GCN Circular 12953
Jang, M., Im, M. (SNU), & Urata, Y. (NCU) We observed GRB 120211A (Sonbas et al., GCN 12920) in SDSS i,z-bands with a 1 m telescope at Mt. Lemmon, Arizona, U.S. The obsevation started at 04:03:00 2012-02-12 UT, ~ 17 hours after the burst alert. We took 4 frames for each filter alternatively with the exposure time 300s. No afterglow candidate was found in the enhanced XRT position (Goad et al., GCN12922) in stacked images of both i and z. We thank the LOAO operator, J. Yoon for this observation.
