Special Notice #47: Increased Activity in P Cyg

May 19, 2007

P Cyg (2014+37A) is the prototype of massive stars with high mass outflow; it is characterized by blue-shifted emission lines along with red-shifted absorption lines. Surprisingly, we've never created a Variable Star of the Season article for this neat star - I'll have to make sure that happens soon.
