November 18, 2010: As was noted by AAVSO observer E. Erdelyi (Carlsbad, CA, USA) in a post to cvnet-discussion, the BL Lac object 3C 454.3 (AUID 000-BDC-612) appears to be undergoing a bright flare; the object was recorded by Erdelyi at V=13.659(0.013) on 2010 November 10.2708 (JD 2455510.7708). The last flare of comparable brightness was observed in 2007, when the object reached V ~ 13.4 around JD 2454335 (late August 2007).
Thanks to the Curry Foundation and NASA for support of the AAVSO International High Energy Network. Thanks to all the observers across the world for their hard work.
The AAVSO has held three Professional-Amateur meetings in collaboration with NASA, Sonoma State University, and New Mexico State University
