follow-up collaboration:
We observed the field of the Swift Swift GRB 121128A (Oates et al., GCN
14007)with AC-32 (0.7m Maksutov) telescope of Abastumani Observatory,
starting on Nov. 28 (UT) 15:28. We took several unfiltered images of 300
s exposure. We detected the afterglow (Oates et al., GCN 14007; Japelj
et al., GCN 14008) in stacked images. The photometry of a the stacked
image is based on USNO-B1.0 stars (R2):
