[vsnet-alert 8693] GRS 1915+105 multiwavelength campaign on Oct 17 and 18

[Yoshihiro UEDA]

Dear VSnet observers, 

Sorry if you receive this mesasage twice. 

I would like to inform that we are organizing a big multiwavelengh
campaigin of GRS 1915+105 on Oct 17 and 18 using Suzaku (Astro-E2),
Integral, Spitzer, RXTE, VLA, and other ground based observatories.
Anyone who are interested in the campaign are welcome to join by
near-infrared or radio observations with your favorite telescopes.
Fast photometic observations in the K band would be particularly
useful. The K-band magnitude of GRS 1915+105 is about 13.


Campaign date and time*: 2005 Oct 17 00:00 to Oct 18 24:00 (UT)
     (*) This is the time that Suzaku will observe the source but
	 the window may shift by a few hours (to the earlier direction only).
	 The Integral/RXTE/Spitzer observations will be arranged to cover
	 this period as long as possible.


The planned/requested observations are as follows:

Space:
 X-ray   Suzaku (PI: Ueda, Suzaku SWG)    Oct 17 00:00 - Oct 18 24:00 UT
 X/Gamma Integral (PI: Jerome Rodriguez)  0:00-8:30 UT on Oct 17 and 18
 MIR     Spitzer (PI: Yael Fuchs)         
 X       RXTE (PI: Ed Morgan)             

Ground:
 Radio	VLA (PI: Marc Ribo)              0:00-6:30 UT on Oct 17 and 18
 Radio	ATCA (DDT requested)            	 	 
 K      Subaru (DDT requested)           
 K      Gunma/Japan (PI: Ueda)
 JHK	IRSF/South Africa (PI: Ueda)


If you are interested in the project and need more information, please 
send an e-mail to Yoshihiro Ueda (ueda at kusastro.kyoto-u.ac.jp). 

We look forward to hearing from you! 

Cheers,

Yoshihiro Ueda (Kyoto University)
