We have acquired  1800s exposure(2 images, 900s each)
in the R-band of the ~8x8 arcmin field centered on the
error box  of the HETE GRB011212 (GCN #1194).
Observations have been carried out  on December 13.15
UT at the Mt. Ekar 1.8 m telescope under no good seeing
conditions, the measured FWHM being ~3 arcsec.
The nominal limiting magnitude reached in the combined
image is R~22.7 (5 sigmas within 3 arcsec aperture).
We  do not detect any object not present in the DSS plate,
with the exception of the asteroid previously quoted in
GCN #1196.
