Canterna (U. of Wyoming) report on behalf of the Red Buttes Observatory (0.6m) GRB Team as part of the FUN GRB Collaboration. We responded to GRB 050908 (GCN 3942) at 08:01:52 UT with a 10 minute I exposure centered on the position of the original Swift-BAT GRB Position under 3.9 arcsecond differential conditions. The source was not detected in the 10 minute I exposure in the same position reported by GCN 3943 (Torii et al.) due to our detection limits. UT Time Since Filter Limiting Magnitude 08:01:52 2:19:21 I 16.056 10 sigma limiting magnitude were derived from the USNO-B1.0 catalogue. This message may be cited.
