February 26, 2016: Dr. Jeno Sokoloski (Columbia University) and Mx. Adrian Lucy (graduate student, Columbia University) have requested AAVSO observations of the jet-driving symbiotic star V694 Mon (MWC 560), which is in outburst, in support of upcoming Chandra observations to investigate the state of the inner accretion disk during this outburst.

The Chandra observations are scheduled (preliminary schedule) for 2016 March 8 (7:17-14:13 UTC) and March 9 (2:20-9:17 UTC).

August 11, 2011: 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.

What are blazars?
