GCN Circular 33293
R. Strausbaugh (University of Minnesota), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the GRB 230204B (Serino et al., GCN 33265) field with the LCOGT 1-meter Sinistro instrument at the Siding Spring Observatory, Australia site, on February 6, from 15:27 to 16:24 UT (corresponding to 38.33 to 39.3 hours from the GRB trigger time) with the SDSS g, r, and i filters. We performed a series of 3x300s exposures in each band. We do not detect a source in any band at the GIT optical counterpart location (Swain et al., GCN 33269), evidence for additional fading compared to early optical detections (Swain et al., GCN 33269; Smartt et al., GCN 33278; Saccardi et al., GCN 33281; Ror et al., GCN 33284). The following upper limits are calculated using the PanSTARRS catalog as reference: g > 22.0 r > 21.9 i > 21.1 These magnitudes are not corrected for galactic extinction.
