          The star V1343 Aquilae is reportedly undergoing a radio flaring episode, 
and optical observations over the next few weeks are encouraged to track 
the optical behavior.  S.A. Trushkin et al report in ATel #3547 that 
observations with the RATAN-600 show a large increase in radio fluxes at 
4.8, 8.5 and 11.2 GHz beginning around JD 2455777 (2011 August 03) and 
continuing through the present.


V1343 Aquilae (also known as SS 433), is a galactic microquasar 
consisting of a stellar mass black hole primary and OB secondary.  The 
system is most famous for emitting relativistic jets generated by the 
black hole during accretion.  It is unclear whether there is a 
relationship between broadband optical and radio activity in this 
system.  However, the object has not been frequently observed during 
this season, and optical observations are encouraged, to provide 
information about the optical state during this radio outburst.


V1343 Aql is located at the following (J2000) coordinates:

	RA: 19 11 49.60 , Dec: +04 58 58.0


Charts for V1343 Aql may be plotted using VSP: http://www.aavso.org/vsp


All observations -- visual and CCD -- are encouraged.  Both CCD time 
series and transformed BVRcIc photometry would be useful.


Please report observations to the AAVSO using the name &quot;V1343 AQL&quot;.
