Cucchiara (U. of the Virgin Islands/College of Marin) report on behalf of a larger collaboration:\n\nWe observed Fermi GRB 200325A (Fermi GBM Team, GCN 27441) with the LCO 1-m Sinistro instrument at the Siding Spring Observatory, Australia site, on March 27, from 12:08 to 12:48 UT (corresponding to 45.25 to 45.92 hours from the GRB trigger time) with the Bessel R and I filters.\n\nWe performed a series of 5x240s exposures in R and I.  We detect a source consistent with other optical detections (Lipunov et al., GCN 27446, Pozanenko et al., GCN 27452) in stacked images.  Using the USNO-B.1 catalog as reference, we obtain the following magnitudes:\n\nR = 21.36 +/- 0.11\n\nI = 20.52 +/- 0.13\n\nThese magnitudes are not corrected for Galactic Extinction.\n\nR.S. is funded by NSF AST grant #1831682",
