"We observed the BeppoSAX WFC error circle of GRB 010214
(Gandolfi, GCN #933) with the AZT-24 1.1-meter telescope
at Campo Imperatore (AQ), Italy.
The J-band observation started at February 15.17928 UT and
the field was imaged for a total exposure time of 2550 sec.
We detected a faint point-like source which is not present
in the Digital Sky Survey-2 IR, R and B plates nor the
2MASS plates. The source is located at:
RA(J2000)= 17h 40m 54.0s
DEC(J2000)= +48d 32' 20"
(uncertainty is 2")
This position lies within the WFC error circle (GCN #933)
and is just outside the BeppoSAX NFI error circle quoted
by Gandolfi GCN #937.
The source was detected with a S/N=12 and had a magnitude of
J=19.1+/-0.3.
Further observations are needed in order to confirm that this
is the IR counterpart of GRB 010214.
