October 31, 2009: Further to AAVSO Alert Notice 353 (aavso-alert-notice-353) (July 11, 2007), Dr. Markus Boettcher (Ohio University) requests optical observations of the blazar 3C 66A during its current high state. Optical observations will support gamma-ray observations by the VERITAS telescope in Arizona. All observations, including visual estimates and CCD photometry are encouraged.
