originally to be closed on April 30, 2001, will be extended to June 15,
2001 to include additional pointings still queuing; an AO-5 program
will start in June 2001.

In AO5, 100% of the AO time will be allocated to Guest Observers Program
open for competition to proposals led by PI's from any country worldwide.

Proposals to participate in the BeppoSAX observing programs should be
prepared and submitted following the instructions given in the documents 
"BeppoSAX Announcement of Opportunity AO-5 for Guest Observer Program" and

Successful proponents are expected to receive the necessary financial
support from their home Institutions or National Agency.

I would appreciate if you could circulate this Announcement to all
interested colleagues within your institution.
