M. Isogai (IAO, NAOJ) and N. Kawai (Tokyo Tech) report with support
of MITuME collaboration:
We observed the field of GRB 081203A(Parsons, et al., GCN Circ. 8595)
with the optical 3-color imager attached to the 105cm Murikabushi
Telescope at Ishigakizima Astronomical Observatory in Japan from
UT 19:52, 5.9 hours after the trigger.
In the co-added images of Ic, Rc, and g' bands, we detected a fading
point source and measured its magnitude. Photometric calibration was
performed using the GSC2.3 catalogs.
The results are following:
MID-MJD MID-UT EXP-T g' Rc Ic
