Observing: Chi Cygni
Sky & Telescope reports:
The red, Mira-type variable star Chi Cygni is having a very unusual maximum right now. It's one of the brightest such variables to begin with (typically peaking at about magnitude 5.2), but now it's about magnitude 3.8, according to many reports to the American Association of Variable Star Observers (AAVSO) in the last two weeks. Writes John Bortle: "This would make the current maximum the brightest in 148 years.I haven't pointed a scope at this one yet but I've been observing it naked eye for the past week or so.
