OUTLINE OF THE WORKSHOP

    We have set up an international workshop at RIKEN entitled
"All-Sky X-Ray observations in the Next Decade
-- a Workshop for ASM and GRB mission in X-ray band --.
  The dates for this workshop are 3 - 5 March, 1997. The workshop is
sponsored by the Science and Technology Agency of the Government of
Japan (STA) in cooperation with the Japan International Science and
Technology Exchange Center (JISTEC).  Regarding the size of the
workshop, we expect it to be relatively small (less than 100
participants) to ensure active discussions.

TOPICS

     Following is the list of topics offered in this workshop.
Each topic will be covered by a few invited talks.  Contributed papers
(talks and posters) are solicited.

     General review of past ASM and GRB missions
     Current missions
     Science of transients
        (GRBs, X-ray bursts, neutron star binaries,
        black hole candidates, CVs, supernovae, AGNs, ...)
     Requirements for future missions
     Scheduled missions
     Proposed missions
