GRB 241204A: DDOTI Upper Limits on the Afterglow

We observed the field of the GRB 241204A detected by Fermi/LAT (Bissaldi et al., GCN [38436](https://gcn.nasa.gov/circulars/38436)) and Fermi/GBM (Godwin et al., GCN 38441) with the DDOTI/OAN wide-field imager at the Observatorio Astronómico Nacional on Sierra San Pedro Mártir (http://ddoti.astroscu.unam.mx) on 2024-12-05 from 02:29 to 03:54 UTC (22.83 to 24.25 hrs after the event), obtaining a total of 48 minutes of exposure in the w filter down to a 10-sigma limiting magnitude of w = 20.6. Comparing our observations to the USNO-B1 and PanSTARRS PS1 DR2 catalogues, we detect no uncatalogued sources within the observed field to our 10-sigma limit within the error radius reported by Fermi/LAT (Bissaldi et al., GCN 38436). We thank the DDOTI technical team and the staff of the Observatorio Astronómico Nacional.
