[vsnet-alert 9181] RXTE SS433 observation campaign

[Kaori Kubota]

Dear VSNET observers,

I apologize if you receive this message more than once.

I am Kaori Kubota at Kyoto University.  Thank you very much for your
cooperation of SS433 campaign in April 2006.  This mail is to announce
another multi-wavelength campaign for SS433 on going.

A radio flare from SS433 occurred on 2006/12/07, MJD=54076.5 (ATel
960).  It suggests that SS433 entered the high state and that
successive flares are following.  Based on previous studies, we expect
that SS433 experiences a second flare in 15.3 +- 7.3 days from the
first flare with a chance of 60 %.

To detect a second flare, the X-ray observatory RXTE and the radio
telescope RATAN-600 are monitoring SS433 everyday.  (see
http://xray1.hp.phys.titech.ac.jp:8000/rj/28 .)  We need optical
spectroscopy/photometry observations covering the second flare,
although the condition for optical observations is, unfortunately,
terrible.


SS433(=V1343 Aql)
 RA:19 11 49.56

If you interested in this campaign and need more information, please
contact me. My email address is kaori.k at kusastro.kyoto-u.ac.jp.

If you get same data of SS 433, please send to me, too !

We look forward to hearing from you !

Best regards,
