We have imaged the BeppoSAX WFC error box for
SAX J2303.2+0015 (also referred to as GRB 991217) as
reported by Muller, et. al. (GCN 474).  Both the 1.0-m
and 1.3-m (wide field) telescopes were used, with
V and R exposures.

Conditions were marginal; light to moderate cirrus
illuminated by the moon prevented individual images
from going deeper than the DSS/POSS-II image.  However,
at that limit, we see no new object within the SAX
4.5 arcmin error box.
