GRB 230205A: LCOGT Optical Upper Limits
Abstract
We observed the GRB 230205A (Ambrosi et al., GCN 33271) field with the LCOGT 1-meter Sinistro instrument at the McDonald Observatory, TX, USA site, on February 6, from 11:51 to 12:23 UT (corresponding to 25.20 to 25.52 hours from the GRB trigger time) with the SDSS r and i filters. We performed a series of 3x300s exposures in each band. We do not detect a source in either band within the XRT enhanced error region (Goad et al., GCN 33275) consistent with other optical upper limits (Hu et al., GCN 33274; Turpin et al., GCN 33282; Wu et al., GCN 33283). The following magnitudes and upper limits are calculated using the PanSTARRS catalog as reference: r > 21.2 i > 20.8 These magnitudes are not corrected for galactic extinction.
