We observed 22 galaxies selected from the NED/CLU list for LIGO/Virgo
S190426c (Chatterjee et al, GCN Circ. 24237) with the Reionization and
Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold
Johnson Telescope at the Observatorio Astronómico Nacional on Sierra San
Pedro Mártir on the night of 2019-04-27 UTC. For each galaxy, we
typically obtained 720 seconds of exposure in g and i filters and 540
seconds of exposure in Y and H filters. Typical 10-sigma limiting
magnitudes are i = 21.2. Our observations are listed below. Visual
inspection reveals no obvious counterpart candidates.

We thank the staff of the Observatorio Astronómico Nacional in San Pedro
Mártir.
