Alert Notice 430: Photometry requested of Blazar-type Quasars 3C 273 and 3C 279

January 11, 2011: Dr. Kirill Sokolovsky (Max-Planck-Institut fuer Radioastronomie, Bonn) has requested the assistance of AAVSO observers to obtain optical photometry of the blazar-type quasars 3C 273 and 3C 279 during 2011. The observations obtained by AAVSO observers will be combined with multiwavelength observations - from radio to gamma-rays - as well as with very long baseline interferometry with the VLBA to obtain a better picture of what these objects are and how they vary.

Search Area Location Chart

Search area location charts will help you organize your nova search observing program. Each area is numbered and represents an area of the Milky Way whose dimensions are approximately 10 degrees of declination by one hour of right ascension. Use these charts to document areas of the heavens you are searching.
