On February 16.078935 UT we observed again the field of the suspect
J-band counterpart of GRB 010214 (Di Paola et al., GCN #939)
for a total exposure time of 7200 sec, with the AZT-24 1.1-meter
telescope at Campo Imperatore (AQ), Italy.
The point-like source reported in GCN #939 was still detected
with a S/N=20 and a magnitude of J=19.1+/-0.1 consistent with the
previous measurement.
The source could be a very red foreground object but at this time,
due to the few existent IR measures of GRBs afterglow, an anomalous
IR afterglow cannot be excluded. Further IR observations are needed.
