K. Kawakami, K. Tokoyoda, Y. Yatsu, Y. Aoki, M. Hayashi, S. Song,
R. Usui, and N. Kawai (Tokyo Tech) report on behalf of the MITSuME
collaboration:
We observed GRB 110915A (S. T. Holland et al, GCN12335)
with the optical three color (g, Rc, and Ic) CCD camera attached
to the MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan.
The follow-up observation was started at 14:29:30, ~69 min after the
BAT trigger.
We did not find any new point source within the enhanced XRT error
circle (P.A. Evans et al., GCNC 12336) in two bands.
Photometric results and are listed below. We used GSC2.3 catalog for
flux calibration.
