Why this object is interesting
This object was my ‘shallow sky’ object in May 2008. While I normally wouldn’t repeat an object I’m making an exception here because this variable star is now brighter than it has been since the summer of 2007.
This star sets just at about 11:00 p.m. in October, so you’ll have to catch it early. R Crb is an irregular variable and the system consists of a star surrounded by a cloud of gas and dust that, from time to time, obscures the star and causes its magnitude to drop from 6 to about 15. Since each magnitude drop is a factor of 2.51 in brightness the 9 magnitude drop represents an almost 250 times drop in brightness. ... Click read more to see the rest of the story.
