The burst had a duration of only 1 s in the GRBM, and thus could be the first BeppoSAX short GRB detection. After a visual comparison with the Digital Sky Survey, no sources varying by more than 0.3 mag were seen to the DSS limit within the BSAX WFC error box. No astronomical filter was used during these observations.
Further analysis is in progress.
All exposures were taken in the R band and lasted 300 s. An analysis of the 70 ksec NFI follow-up, performed about 8 hours after, is being carried on. Further radio observations are underway to determine whether the source is variable or not. The data do not allow to draw a useful constraint about the variability of this source. Since the error box is at low Galactic latitude, we report here on the results of a search for very red objects.
