We observed GRB 110503A (Stamatikos et al., GCN 11991) in R-band
with a 1.0-m telescope at Mt. Lemmon, Arizona. The observation
started at 05-04-03:24:30 UT. We detect the afterglow with a
magnitude at R ~ 20.28 +- 0.09 mag (mid-time of ~10.0 hrs after
BAT alert) based on the photometry calibration star reported by
Updike et al.(GCN 12001).
Further analysis of the data and the follow-up observations of
the object is ongoing. We thank the LOAO operator, I.-K. Baek
for her assistance with the observation.
