ASCA weekly
Dear ASCA users,
Attached below please find a revised ASCA schedule for the period of
September 21 - October 4, 1997. The revision was made to get better
fits for the coordinated time critical observations and to add one time
critical observation of Comet Hale-Bopp, for which early observation
is requested (at this period instaslled the sun angle is 69 degrees, then
the condition is not ideal for the SIS observation).
