Monitoring of HBC 722 and VSX J205126.1+440523 Requested

Active Dates: Oct. 1, 2010 – Dec. 31, 2011


Abstract:

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.

Justification:

Calibrated, transformed photometry is very important to accurately determine color changes because of the dust clouds in which these objects are embedded.
