report on behalf of the Wyoming Infrared Observatory GRB Team as part of
the FUN GRB Collaboration.  We responded to GRB 050908 (GCN 3942Loading...
 
 ) 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 3943Loading...
 
  (Torii
et al.).  Zero points were calculated using the USNO B1.0 catalogue.
