TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  4472
SUBJECT: GRB 060110: ROTSE-III Confirmation of Optical Counterpart
DATE:    06/01/10 14:31:47 GMT
FROM:    Wiphu Rujopakarn at U Michigan/ROTSE  <wiphu at umich.edu>

W. Rujopakarn (U Mich), T.A. McKay (U Mich), F. Yuan (U Mich), H. Swan 
(U Mich), D.A. Smith (Guilford), S. A. Yost (U Mich) report on behalf 
of the ROTSE collaboration:

ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB 
060110 (Zane al. GCN 4463). The first image was at 08:01:44.8 UT, 27.1 
s after the burst (9 s after the GCN notice time). Imaging is shallow 
due to the brightness of the Moon. The unfiltered images are calibrated 
relative to USNO A2.0 R-band. We detect the source reported by Bloom 
(GCN 4471) near the limiting magnitude of the early coadded exposures. 
It was ~15.5 mag at about 50 s post-trigger, in an image at limiting 
magnitude 16.0

Further data analyses are in progress.
