behalf of a larger collaboration:
We observed the field of GRB 120212A (Sonbas et al., GCN 12930) using
the 2.5m Nordic Optical Telescope (NOT) equipped with the ALFSOC
camera. We obtained 4x200s R-band images with a median time 19:52:24
UT on 2012-02-12, i.e., 10.7 hrs after the BAT trigger.
The optical afterglow of this burst (Guidorzi et al., GCN 12932;
Hoversten et al., GCN 12933; Kawabata et al., GCN 12935; Kuin et al.,
GCN 12940) was clearly detected in our stacked image and had R ~ 20.1
mag calibrated with nearby stars in the USNO B1 catalog.
