We observed the field of GRB 120422A (Troja et al., GCN 13243) with the
0.6m Super-LOTIS telescope at KPNO beginning 77 seconds after the
trigger under good conditions. We do not detect the OT (Cucchiara et
al., GCN 13245; Kuin & Troja, GCN 13248) in the R band. Limiting
magnitudes are given below, compared to the USNO B1.0 catalog.
