ASCA Weekly

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

Dear ASCA users:

We have replaced the degraded S1 Gyro with a spare S2 Gyro on Nov. 29. 
The on-board software for attitude control was switched for the combination 
of X-, Y-, and S2-gyros and the attitude was successfully locked to a sky 
appointed by the tracking stars. Tuning of on-board parameters for attitude 
control and test maneuvers have been in progressing.  A few targets in the 
direction suitable for the test maneuver will be observed after December 1. I 
expect that we are able to restart regular observations from December 3 or 4 
along the announced schedule. The long-term timeline will be revised when 
we are convinced of stable maneuver operation.

In the following I have attached the observation plan for the week of 
December 10 - 17.

Regards,
F. Nagase
