"Using the 2.56-m Nordic Optical Telescope (+ALFOSC), La Palma,
we have obtained R-band imaging of GRB 010214 (Gandolfi et al.
GCN #932), starting ~20 and ~45 hours after the burst:

UT              Filter    Exp.time   Seeing      Limit
======================================================
2001 Feb 15.22    R       6x300s     1.2" FWHM  R~21.3
2001 Feb 16.24    R       6x300s     0.9" FWHM  R~23.5

No candidate GRB counterpart is detected inside the 
1.5' SAX/NFI error-circle (Gandolfi et al. GCN #937)
to R~21.3.

The possible infrared candidate reported by Paola et al. 
(GCN #939) is detected at R~22.1 in the Feb 16 image.
We find no object at the position of the possible optical 
candidate reported by Zhu and Xue (GCN #938)."
