ASCA weekly

[Fumiaki NAGASE <nagase@astro.isas.ac.jp>]

Dear ASCA users:

I am sending an ASCA observation schedule for the period of August 26 
to September 6. Next release of weekly ASCA schedule will happen after
the week of August 6.  Those who have observations in August and are
planning to take a long vacation in July-August should contact with
ISAS/NASA contact scientists as early as possible to confirm their 
observation plan, such as pointing coordinates, observation modes etc.

The time critical target IRAS 03158+4227 are allocated in this week 
in coordination with the CGRO/OSSE observation. The Sun-source
angles of the two pointings are 72 and 75 degrees, respectively. Since
this angle is significantly smaller than 90 degree (or telescope is inclined
toward the Sun),  significant degradation of the SIS data is suspected 
due to the DFE level change at the day-night transitions of the satellite 
and the light leakage on some chips of the CCD cameras. 
The observer of this target should examine carefully the SIS observation 
modes in consulting with the contact scientist. We do not guarantee the 
possible degradation of the SIS data for this kind of cases that are
due to the requested time constraint.
