Cucchiara (UVI/College of Marin) report:\n\nWe observed the field of GRB201024A (F. E. Marchall et al., GCN 28761) with\nthe\n0.5m Virgin Island Robotic Telescope (VIRT) at the University of the Virgin\nIslands' Etelman Observatory on 10-24-2020 starting at 06:39:34.2 UT (T+3.3\nhrs). We performed a series of exposures in R filter with a total exposure\nof 1430 s. The weather conditions were partly cloudy during the hours of\n\nobservation with an average arimass of 1.5.\n\n\nWe find no new source within the enhanced XRT position error circle\n(P. A. Evans et al., 28770) and report the following 3-sigma upper limit:\n\nT_mid       ||Exposure     ||Filter      ||Limit\nT+ 5 hrs    ||1430s          ||R            ||>18.9\n\nThe limit is estimated from comparison to nearby USNO B1 stars and is not\ncorrected for Galactic extinction. The VIRT is still in the commissioning\nphase.\n\n\n\nThis work is supported by NASA-MUREP-MIRO grant NNX15AP95A, NSF EiR AST\nAward 1901296, and NSF HBCU-UP AST Award 1831682.
