GRB030723: Upper limits from historical observations.
W. M. Wood-Vasey, Lawrence Berkeley National Laboratory, using images
obtained by R. Bambery, S. Pravdo, M. Hicks, and K. Lawrence
(Near-Earth Asteroid Tracking project, Jet Propulsion Laboratory),
reports historical upper limits for the optical transient for
GRB 030723 of Fox et. al (GCN #2323) from images taken with the
Palomar Oschin 1.2-m telescope from 2001 Aug 30 -- 2002 Sep 9.
A co-addition of these images (taken 2001 Aug 30, Oct 8, 2002 Jul 29,
Aug 13, Aug 20, Sep 9) shows nothing at this location to a combined
limiting unfiltered magnitude of 21.62 (S/N = 3).
The co-addition is available at:
http://supernova.lbl.gov/~wwoodvas/GRB/#GRB030723
The quoted magnitude represents a calibration of the unfiltered NEAT
observations to the observed stars in the 0.25 sq. deg field of the
component images to the "red" USNO-A1.0 catalog.
