LIGO/Virgo/KAGRA S241125n: DDOTI Optical Upper Limits

We observed the field of LIGO/Virgo/KAGRA S241125n (LVKC, GCN 38305) with the DDOTI/OAN wide-field imager at the Observatorio Astronomico Nacional on Sierra San Pedro Martir (http://ddoti.astroscu.unam.mx) on the night of 2024-11-26 UTC. We performed two pointings which include the position of the Swift/GUANO candidate counterpart (DeLaunay et al., GCN 38308) and the 5 X-ray sources reported by XRT (Page et al., GCN 38324). DDOTI observed from 02:01 UTC to 04:17 UTC (from T+25.0 to T+27.2 hours after the event) down to a 10-sigma limiting magnitude of w = 20.4. Comparing our observations to the USNO-B1 and PanSTARRS PS1 DR2 catalogs we detect no uncatalogued sources within the observed field to our 10-sigma limit.
