TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3125 SUBJECT: GRB 050319:Near IR afterglow DATE: 05/03/20 11:36:41 GMT FROM: Koshy George at PRL Koshy George,Jinesh Jain,N.M.Ashok,T.Chandrasekhar (Physical Research Laboratory,India) We report on the detection of near infrared afterglow of GRB 050319 using NICMOS camera coupled with 1.2m telescope of Physical Research Laboratory at Gurushikar, Mt.Abu, India. The observations started at 15:41:00 UT on 19 March in J-band filter at a 4'* 4' field of view shows a probable Infrared candidate at the error region of optical afterglow candidate (GCN 3116 & 3117). We had taken a net fourty minute exposure and the source which was present in our first 20s frame was found to be faded down to our observational limits with in 4min (four frames of each 60s exposure). Preliminary analysis and on comparison with two near by stars present in our field shows that the near infrared afterglow candidate corresponds to a J-band magnitude ~ 13 at 15:41:20 UT
