TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 3957
SUBJECT: WIRO observations in I of GRB 050908
DATE: 05/09/09 19:28:11 GMT

report on behalf of the Wyoming Infrared Observatory GRB Team as part of
the FUN GRB Collaboration. We responded to GRB 050908 (GCN 3942) at
07:40:25 UT with a 2 minute I exposure and at 10:25:35 UT with a 4 minute
I exposure centered on the position of the original Swift-BAT GRB Position
under 1.5 arcsecond photometric conditions. The source was detected in
the 2 minute I exposure in the same position reported by GCN 3943 (Torii
et al.). Zero points were calculated using the USNO B1.0 catalogue.
UT Time Since Filter Magnitude
07:40:25 1:57:54 I 18.410 +/- 0.128
The source was no longer detected in the 4 minute I exposure.
UT Time Since Filter Limiting Magnitude
10:25:35 4:43:04 I 18.620
10 sigma limiting magnitude were derived from the USNO-B1.0 catalogue.
