Pereira\nreport on behalf of the LOTIS collaboration:\n\nSuper-LOTIS observed the HETE/IPN error box of GRB 010921\n(GCNC #1096, #1097) on 09/22/2001 starting at 03:05 UTC, \n21.8 hr after the burst. Super-LOTIS is a 0.6 m telescope \nlocated at Kitt Peak. These observations were made with a \nclear filter and an effective integration time is 1000 s. \nWe detect the afterglow reported by Price et al. (GCNC #1107) \nat 2 epochs. The magnitude of the afterglow is calibrated \nagainst R band secondary standards reported in GCNC #1100 \nby Henden.\n\n\tUTC\t\tRopen\n\t9/22/01 03:05\t19.4 +/- 0.2\n\t9/22/01 06:25\t19.9 +/- 0.2\n\t9/23/01 03:05\t> 21.2 +/- 0.3\n\t9/23/01 06:27\t> 21.2 +/- 0.3\n\nFurther analysis is in progress.\n\nThis message can be cited.",
