GRB 010324 observation at Nyrölä Observatory (FIT)
We imaged the field of GRB010324 briefly during a CCD
Messier-Marathon (82 objects imaged in single night!).
Above is our combined image taken at March 24, 2001 22:45-22:55 UT.
It is summed from nine 60 s unfiltered exposures with 3x3 binned SBIG
ST7E on 16-inch Meade LX200 @ f3.3.
No new objects visible by quick inspection, image reaches about as deep
as DSS2 (mag 19 or so).

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
