C. Wu, X. H. Han on behalf of EAFON report:
We began to reobserve GRB120326A (Siegel et al., GCN Circ. 13105)
with Xinglong TNT telescope in R-band at 20:30:50.7 (UT), Mar. 27th 2012.
43.7 hours after the burst. The optical counterpart (e.g. Klotz et al. GCN Cir 13107)
was still clearly detected with a brightness of R=19.32 mag, relatively to USNO B1.0 R2 mag.
Comparing to the observation last time (Xin et al. GCN Cir. 13131),
the brightness decayed by a magnitude of 0.76 mag during these two epoch.
Further observations are planed.
