K. Kinugasa (Gunma Astronomical Observatory) and K. Torii (Osaka U.) report:
The error region of GRB 060204B (Falcone et al. GCN 4655) was imaged
by the robotic 0.25m GETS telescope in the Gunma Astronomical Observatory.
Unfiltered imaging started at 14:36:23 UT (119 s after the BAT trigger)
and 30 s integration was repeated.
We did not detect the optical afterglow (Guidorzi et al. GCN 4661; Moon
& Cenko GCN 4667) and the following 3-sigma upper limits are derived relative
to USNO-A2.0 R mag.
