We have observed the position of the GRB 130603B afterglow at multiple
epochs with the AMI Large Array at 15 GHz. Our initial observation was
for one hour starting at 15:53:42 UT on June 3rd, just under 5 minutes
after the GRB trigger time (GCN 14735). We also made longer observations,
at 3.12 and 22.8 hours post-burst. We do not detect the afterglow
in our preliminary reductions.
Preliminary analysis gives 3-sigma upper limits as follows:
Start (Hrs post burst) | Duration (hrs) | 3-sigma upper limit
---------------------------------------------------------------------
0.08 | 1 | 0.6 mJy
3.12 | 3 | 0.21 mJy
22.8 | 3 | 0.3 mJy
Further observations are scheduled.
These observations were initially triggered via the system described in
Staley et. al (2013, MNRAS, 428, 3114).
