BeppoSAX ALERT: possible GRB020411

On Apr. 11, 01:49:05 UT a further possible GRB has been
detected in BeppoSAX WFC1. Unfortunately GRBM was again switched off at
that time. A Quick Look analysis seems to confirm the X-ray Flash or GRB
nature of the event.

Preliminary coordinates are:

R.A.(2000)= 78.111
DEC.(2000)= 68.257

The error radius  is 5'.

April 11 BeppoSAX event (GRB020411) is likely not a GRB

A more refined analysis of April 11 event (possible GRB020411) gives
results which are inconsistent with the GRB hypothesis. Therefore we
cannot confirm the nature of the burst and conclude that the inccrease of
counts could be related to solar activity.

report on behalf of the SARA consortium: 

We imaged the error-circle of "GRB020411" (Gandolfi et al., GCN1354)
with the SARA 0.9m telescope at KPNO on 02/04/11, starting eight hours
after the "burst". We covered the error circle with 4X3 three minute 
exposures in the I band. Comparison with the DSS did not reveal any
new sources. A more refined analysis of this event (Gandolfi et al.
GCN1356) suggests that this event was not a GRB. 

No further Observations are planned for this event.
