BeppoSAX MAIL n. 01/11: ALERT: Possible X-ray rich GRB011030


On Oct. 30, 06:28:02 U.T. a  faint transient has been detected
by the WFC1 aboard BeppoSAX, without counterpart in the GRBM.

Preliminary  coordinates from WFC are:

R.A.(2000)= 310.927
DEC.(2000)= 77.293

The error radius at this stage of analysis is 5'.

A preliminary analysis of quick-look data shows that the event could be an
X-ray rich GRB, but the low galactic latitude and the presence of a faint
Rosat source (1RXS J204310.8+77172) inside the error box can not exclude
the x-ray burster nature of the source.
We are not planning a follow-up observation of this burst, due to the
on-going testing phase of gyroless attitude control system.
