October 1, 2010: Dr. Colin Aspin (U. Hawai'i) has requested the help of AAVSO observers in performing long-term photometric monitoring of the two new young stellar objects (YSOs) in Cygnus, HBC 722 and VSX J205126.1+440523 (see AAVSO Special Notice #216).  

The AAVSO offers several methods of getting the news out that your favorite star has been observed, or something odd and interesting is going on in the sky.
