P.A. Price (RSAA/ANU) and D.W. Fox (Caltech) report on behalf of a
larger collaboration:
"We have imaged the full localization region of GRB030131 (GCN 1838)
with the Palomar 48-inch Oschin Telescope + NEAT camera, in six 120s
exposures over 10:42 UT to 11:31 UT. The summed image from these
unfiltered exposures reaches a limiting magnitude of R~21 mag as
estimated from the magnitude of several USNO-A2.0 stars in the image.
We identify no new sources by reference to images from the Second
Digitized Sky Survey. We estimate the magnitude of any new source to
be R>20 mag at the mean epoch of our observations, 11:16 UT, which is
3.62 hours after the burst."
