Williams (MMTO), on behalf of the\nSuper-LOTIS Collaboration, report:\n\nThe 1.54m Kuiper telescope began observations of the error region of\nGRB 071025 (Swift trigger 295301, Pagani et al. GCN 6986) at 04:37:08\nUT, approximately 28 minutes after the trigger.  Observations were\nobtained in the V, R, and I-bands. The afterglow first reported by\nRykoff et al. (GCN 6987) is clearly visible in the individual early R\nand I band images but not in the V-band images or in the sum of the\nV-band images.  Observations continued until 09:47:09 UT.\n\nThe aperture photometry results below were obtained from sums of\nindividual images using nearby stars in the USNO-B1.0 and NOMAD\ncatalogs. Further analysis of additional epochs is continuing.\n\nFilter UT-Start       UT-End        exp (s) magnitude error\nR ---- 04:37:08 ----- 04:41:30 ---- 150 --- 18.7 +/- 0.1\nR ---- 04:42:14 ----- 05:02:40 ---- 1080 -- 19.3 +/- 0.1\nR ---- 05:03:12 ----- 05:24:11 ---- 1080 -- 19.8 +/- 0.1\n\nV ---- 05:43:38 ----- 06:07:46 ---- 1200 -- < 22.0\n\nI ---- 05:25:05 ----- 05:42:39 ---- 960 -- 18.2 +/- 0.1\nI ---- 08:01:20 ----- 08:55:41 ---- 3000 -- 19.9 +/- 0.15\n\nThis message may be cited.",
