report on behalf of the AAVSO International GRB network:

We have observed the error box for the RXTE ASM GRB010324
(Hurley et al., GCN 1011) with a variety of telescopes
and image scales.  Based on comparison with the POSS-II
red plate as digitized at USNO, we find no new object
within the error box.  A log of observations is given below.
For the Filter field, C=unfiltered, R=Cousins R,
I=Cousins I.  The Delay field is the time since
burst (010324.484 UTD).  Several of these composite images
are available at ftp://ftp.aavso.org/grb/
