J. Wang, C. Wu, J. S. Deng report:
We observed GRB 160225A (Siegel et al. GCN 19075) with
80cm TNT telescope, located at Xinglong obervatory, China,
at 14:24:26 UT, about 3.5 min after the burst.
The optical afterglow (Wiersema et al., GCN 19082) near the
enhanced XRT errorbox (Goad et al., GCN 19082) was detected
in our white and R-band images.
The brightness of the optical afterglow is about 17.58 mag
at the mid time of 3.67 min afer the burst, calibrated by
the USNO B1.0 star (RA=10:56:59.4 DEC=+53:40:45 R2=15.26mag).
We thank excellent support of the Xinglong 80cm TNT staff,
particularly YunPeng Wang.
