 The R-band observations of GRB 051021 (Yoshida et al., GCN 4116) were
taken by Lulin 1-m telescope, Taiwan.  The optical afterglow reported
by Fox et al.(GCN 4120) was detected clearly in our R-band
images. Compared with USNOB stars, the R band magnitude of afterglow
is about 19.8 at 15.859 UT (~ 2.48 hrs after the burst).

Further observations are on going.
