AAVSO: Special Notice #9


Kaori Kubota (Kyoto University) has asked for observations
of V1343 Aquilae (a.k.a. SS433) in support of an observing campaign
using the Suzaku X-Ray satellite. V1343 Aql is listed as an
eclipsing X-Ray source according to the GCVS 3rd Edition. It
consists of an early type star and a neutron star or black hole with
relativistic jets detectable at X-Ray and radio wavelengths. Kubota
reported it currently at 14th magnitude. It's location is:

R.A.: 19:11:49.6  Decl.: +04:58:57.9 (J2000)

Observations from now until April 5 are requested to determine
the orbital phase before the Suzaku observations, which are
scheduled for April 5 and 8.

AAVSO charts, using a sequence from Leibowitz and Mendelson (1982),
