GCN 7525) was observed\nwith the 150 cm telescope of the Gunma Astronomical Observatory.\nStarting at 09:49 UT (1.75 hours after the trigger), Rc frames\nwere acquired for 9 x 3-min exposures  under a poor seeing\n(~4.5arcsec) condition.\n\n The UVOT position is close to a star, so that the field are affected\nwith the light from this star. We do not identify the optical counterpart\nreported by UVOT to limiting magnitudes of Rc=20.7 relative to USNO-B1.0 R2\nmagnitudes at the meantime of 10:08 UT.\n\n Combining the results reported by Guidorzi et al. (GCN 7526), the decay\nindex is > 0.9, which is consistent with the intial index reported by\nGuidorzi et al. (GCN 7526).",
