ASCA weekly

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

Dear ASCA users;

We have decided to observe Cyg X-1 as TOO of ASCA during the high state
currently undergoing. The observation is made on May 30 by using the span 
once allocated for NGC 4258 pointing No. 2 (JPN Pri-B, PI; Y. Ishisaki). 
The third pointing of NGC 4258 currently allocated on June 5 is replace 
to the second pointing and the third pointing of NGC 4258 will be shifted 
either to the late June or to the next window  in fall. This change does 
not arise any impact to the observation time of other targets allocated 
in this week as seen below.
