Visible Outburst of Star Z Canis Major

Z Canis Major in outburst! Visible with a simple binoculars.

Look up to the sky astronomy fans! If moon won’t obstruct your view, you will have the chance to observe the outburst of the bright variable star Z Canis Major. Thanks to the two orders of magnitude it acquired it will be in sight even with binoculars or small telescopes.
The binary variable Z CMa is erupting, and has a magnitude of 8.5.
The observations of the AAVSO International Database, confirmed the eruption some hours ago. By the way, this eruption could be started in April 2010, at that time it started to slightly increase the brightness reaching 10.7.

The current eruption is as bright as it was the one in 2008, the brightest we’ve ever seen. Z Canis Major is an interesting object mainly because it is a binary star consisting of a Herbig Be and FU Ori stars.

Observations of Z CMa are strongly encouraged, both during the current eruption and in the future.
