On January 3, 2010 Gary Poyner, an amateur astronomer, reported to the VSNET mailing list Japanese UV Persei the outbreak of a cataclysmic variable star popular enough variability. Part of its charm is its location, close to the beautiful double cluster in Perseus.
However
UV Per is expected. And it can happen between 300 and 400 days at rest, at its minimum brightness, about 17-18 in V-band magnitude (which is practically impossible to observe visually through an eyepiece, just register on CCD images). Enters suddenly burst and the magnitude is almost 11, ie, it becomes about 250 times brighter (¡!).
At the time I took the image illustrating this post, last night, the star is already declining in brightness, with a 13.33 magnitude in V filter photometry gave me.
The observation of variable stars, as reader you can imagine, has a good deal of patient waiting.
