TITLE: GCN CIRCULAR NUMBER: 33333 SUBJECT: GRB 230204B: Lowell Discovery Telescope Observations DATE: 23/02/17 00:41:17 GMT FROM: Brendan O'Connor at UMD B. O'Connor (UMD, GWU), E. Hammerstein (UMD), S.B. Cenko (UMD, NASA-GSFC), E. Troja (UTV, ASU), S.Dichiara (PSU), J. Durbak (UMD, NASA-GSFC), A. Kutyrev (UMD, NASA-GSFC), S. Veilleux (UMD), I. Andreoni (UMD, NASA-GSFC), and G. Srinivasaragavan (UMD): We observed the field of GRB 230204B (Serino et al. GCN 33265; Kennea et al. GCN 33267) using the Large Monolithic Imager (LMI) on the 4.3m Lowell Discovery Telescope (LDT) at Happy Jack, AZ. Observations began on February 13th, 2023 at 11:05:48 UT at airmass 1.8 under seeing of ~2" with total exposure 2400 s in i-band. At the location of the optical counterpart (Swain et al. GCN 33269), we do not detect any source to depth i>23.7 AB mag. Magnitudes are calibrated against the SDSS catalog and are not corrected for Galactic extinction. We thank the staff of the Lowell Discovery Telescope for assistance with these observations.
