Following the detection of a possible near-infrared counterpart J-GEM24a (GCN #36333) to LIGO/Virgo/KAGRA S240422ed (GCN #36236, #36240), we visually inspected the position of this candidate in the images obtained with the DDOTI wide-field imager at the Observatorio Astronomico Nacional on Sierra de San Pedro Martir (http://ddoti.astroscu.unam.mx) on the night of 2024-04-23 UTC (GCN #36256).
We found no significant optical counterparts at the position of this source in our stacked unfiltered image, down to a limiting 5-sigma AB magnitude of w=20.2.
We thank the staff of the Observatorio Astronomico Nacional in San Pedro Martir.
