We have observed the afterglow candidate of GRB 020305 (GCN #1267
Not found
 
 
)
with the Subaru 8.2m telescope atop Mauna Kea at 2002 March 12.6 UT
(7 days after the burst).  Several R and I-band images were taken
with the observing instrument FOCAS.  The limitting magnitudes were
approximately R=26 and I=25, respectively.

We detected a point source of R=22.6 and I=22.1 within 1 arcsec
from the position reported in GCN #1267
Not found
 
 
.  7 USNO stars were used
for R-band relative photometry.  The magnitude in I-band, however,
was estimated by simply converting the observed intensities
empirically to the magnitude.  Elongated diffuse nebulosity can be
seen toward the northeast direction from the candidate.
