GCN Circular 7700
D.K. Sahu, G.C. Anupama (IIA, Bangalore), Kuntal Misra (ARIES) report. The field of GRB 080506 (Baumgartner et al., GCN 7685) was observed using HFOSC mounted on the 2-m Himalayan Chandra Telescope, Indian Astronomical Observatory, India. A series of 300sec exposures were taken in R-band between 20:45 UT and 23:00 UT on 06/05/2008. The optical counter part is detected in all our frames. Using the calibration by Kawabata et al. (GCN 7686), the estimated R band magnitude of the optical counter part is 20.13+/-0.1 mag at 20:47UT. The optical counter part faded by ~ 0.6 magnitude during our observations.
