We have observed the afterglow candidate of GRB 020305 (GCN #1267)
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. 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.
