Subject: MINE OBSERVATIONS OF CYG X-1

Dear colleagues,

INTEGRAL is performing as expected. As part of the commissioning time 
it will point to Cygnus X-1 for 1 million seconds between November 24 
and December 6. In the context of the "MINE" collaboration 
(http://elbereth.obspm.fr/~fuchs/mine.html), monitoring programs are 
recommended for this period. 
 
On the other hand, we have selected the following periods as the best 
for detailed observations: 

November 26   00:40 to 23:50    UTC
December  4   00:00 to 24:00    UTC

For these two days proposals to NRAO VLA & VLBA were submitted asking  
the data to be public. The same was requested to RXTE. 
Observing Cygnus X-1 with other telescopes would be of much interest.  
The X-ray spectrum of Cygnus X-1 is hardenning and this may be a great 
opportunity. 

For further information, please, be in contact with Yael Fuchs
 (yfuchs@discovery.saclay.cea.fr). 


Best regards,
Felix Mirabel & Yael Fuchs
