TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  4241
SUBJECT: GRB 051109b: GETS observation
DATE:    05/11/10 08:38:00 GMT
FROM:    Kenzo Kinugasa at Gunma Astro. Obs/Japan  <kinugasa at astron.pref.gunma.jp>

K. Kinugasa (Gunma Astronomical Observatory) and K. Torii (Osaka U.) report:

 The error region of GRB 051109b (Tagliaferri, et al. GCN 4222) was imaged
by the robotic 0.25m GETS telescope in the Gunma Astronomical Observatory.
Unfiltered imaging started at 08:52:45 UT (13.1 minutes after the trigger)
and 30 s integration was repeated.

 We do not identify a new object within the BAT error region (Hullinger, et
al. GCN 4222) and the following 3-sigma upper limits are derived relative to
USNO-A1.0 R mag.
