"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)."
