Alpha Centauri is the nearest star to the unaided eye, and the third brightest of the sky. A small telescope reveals it to be a beautiful double system: two stars similar to our Sun revolve each other in the span of a human lifetime. Because of their relative proximity, angular separation and position angle of the two components change notably in the matter of years, making this system particularly interesting to observe. This year, in November, the angular separation reaches a minimum of only four arcseconds.
On May 23, amateur astronomers across central Europe are in for a treat: Two asteroidal occultations within one hour, without having to change your seat. This is a pretty rare occurrence, as such events are only visible in a rather narrow paths on the ground.
