C. Rodgers, E. Hausel, and R. Canterna report on behalf of the Red Buttes Observatory GRB Team as part of the FUN GRB Collaboration. We responded to GRB 050713A (Swift trigger 145675; 4:29 UT) at 04:54 UT with a series of 5 minute R and I exposures centered on the location of the original Swift-BAT GRB position under excellent conditions. We did not observe the afterglow candidate (Malesani GCN 3582) brighter than the following magnitude limits:
UT Time Since Filter Limiting
Start GRB Magnitude
04:56 0:27 R 19.4
05:01 0:31 I 18.2
06:02 1:33 R 19.4
06:08 1:38 I 18.7
10 sigma limiting magnitudes were derived from the USNO-B1.0 catalogue
