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:\n\nUT      Time Since   Filter     Limiting \nStart   GRB                      Magnitude \n04:56   0:27          R           19.4 \n05:01   0:31          I           18.2 \n06:02   1:33          R           19.4 \n06:08   1:38          I           18.7 \n\n10 sigma limiting magnitudes were derived from the USNO-B1.0 catalogue",
