Adria C. Updike, Dieter H. Hartmann (Clemson University), Gary Henson
(ETSU), Robert Mesler, Christina Bunker, and Jason Carson (ETSU/SARA REU
program) report:
We imaged the field of GRB 070610 (GCN 6489, Pagani et al.) beginning 10
hours and 53 minutes after the trigger (281993) with the SARA 0.9m at
Kitt Peak under decent weather conditions. In 30 minutes of stacked
exposures in the R band, we do not detect the optical transient (GCN
6492, Stefanescu et al.) down to a limiting magnitude of 19.8 +/- 0.2
based on calibration to 8 USNO B1.0 stars.
Due to the possible galactic nature of this source (Kann et al., GCN
6505), we encourage further observations.
