V. Zach Golkhou (ASU), Nat Butler (ASU), Neil Gehrels (GSFC), Alexander Kutyrev (GSFC), William H. Lee (UNAM), Eleonora Troja (GSFC), and Alan M. Watson (UNAM) report:

We observed the La Silla Quest candidate (GCN 18473; RA = 2.865, DEC = -6.4273), with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio 
Astron�mico Nacional on Sierra San Pedro M�rtir from 2015/10 27.11 to 2015/10 27.13 UTC. We obtained a total exposure of 24 minutes on this target.

The source is cleanly detected in the r, i, and z bands.  We find r = 17.14 +/- 0.01, i =  17.37 +/- 0.01, and z = 17.39 +/- 0.06.  These magnitudes are in the AB system and are not corrected for Galactic 
extinction.

We thank the staff of the Observatorio Astron�mico Nacional in San Pedro M�rtir.
