ABSTRACT

"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)."
