We observed GRB 120326A (120326A et al., GCN 13105)
in R-band with a 1 m telescope at Mt. Lemmon, Arizona, U.S.
The obsevation started at 09:06:33 2012-03-26 UT, ~ 8 hours
after the burst alert.
We totally took 6 frames with 300 sec of exposure time and found
a bright optical afterglow in each frame (Im et al. GCN 13117,
Klotz et al. GCN 13107, Guidorzi et al. GCN 13111, Walker et al. GCN 13112,
Dintinjana et al. GCN 13113, Kuin et al. GCN 13114).
Preliminary photometry values are shown below. The R magnitudes were calibrated
with three nearby USNO B1.0 stars, USNO-B1.0 1592-0143334, 1592-0143322,
and 1592-0143349
