We obtained 3x200s exposures with the SDSS r’ and SDSS i’ filters starting at 2024-12-18 03:33:56 UT, approximately 3.4 hours after the trigger.\n\nWe do not detect any new sources at the Swift/XRT enhanced position (Beardmore et al., GCN 38604). The 3-sigma limiting magnitudes on the stacked images are r > 20.9 mag and i > 21.0 mag, calculated using the nearby PanSTARRS secondary standards as reference. The photometry was not corrected for extinction.",
