(GCNC #1096, #1097) on 09/22/2001 starting at 03:05 UTC,
21.8 hr after the burst. Super-LOTIS is a 0.6 m telescope
located at Kitt Peak. These observations were made with a
clear filter and an effective integration time is 1000 s.
We detect the afterglow reported by Price et al. (GCNC #1107)
at 2 epochs. The magnitude of the afterglow is calibrated
against R band secondary standards reported in GCNC #1100
by Henden.
