Optical observations of GRB 130427A
We're pleased to note that GCN Circular #14490 has been published, detailing time-series photometry of the bright GRB 130427A by Patrick Wiggins. His observations provide a comprehensive record of the three hours of the early evolution of this incredibly bright afterglow.
Congratulations to Patrick on his observations!
Special Notice #223: BL Lac object 3C 454.3 undergoing bright flare
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).

High Energy Network Overview
The AAVSO International High Energy Network came about as an evolution of the AAVSO International GRB Network. The GRB Network was established at the First High Energy Workshop for Amateur Astronomers in April, 2000. The GRB network was a great success, detecting many GRB afterglows and discovering a few on our own. The follow-up of GRB optical afterglows continues to be a major focus of the Network today.
