M. Yoshida, K. Yanagisawa, Y. Shimizu, S. Nagayama, H. Toda (OAO, NAOJ)
and N. Kawai (Tokyo Tech) report on behalf of the MITSuME collaboration:
The Ic band photometry results reported in GCN 7082 are not correct.
The correct values are 1.5 magnitude brighter than those in GCN 7082.
We made a mistake in calculating the zero point magnitudes of our Ic
band frames. We also checked the results of other two bands (g' and Rc)
photometry carefully and found they are correct.
Please discard the results of GCN 7082. The reviced data are following.
Observation date: 2007-11-12 UT
