We began to observe GRB120219A (Swenso et al. GCN 12964 )
with Xinglong TNT telescope at 14:32:15 (UT), 127 sec after
the burst. A serveral white and R-band were obtained.
After combining 11*300s R-band images, a new marginal source was
found within the errorbox of X-ray counterpart ( Swenso et al. GCN 12964).
Its coordinates ( RA and Dec ) are 08:39:09.55 51:01:56.5 (J2000)
with an uncertainty of about 1 arcsecond.
The brightness of the source is estimated to be about
21.5 +/- 0.3 mag relatively to USNO B1.0 R2 mag
at the mean time of 37 min after the burst.
Further observations and confirmation are encouraged.
