Can somebody take a look at Alpha Ursa Major, the closest pointer star towards polaris in the big dipper. Visually, tonight 3-9-15, it looks like it has a naked eye companion. It's a multiple star system but the companions are faint:

Hi Rod,
I'll take a look this evening, but the light pollution is so bad here in Colorado Springs, that I'll have to travel or just get out the C8. If it is a naked eye event that would be pretty cool.

There's a mag ~7 about 10 arc-min away in the approx direction toward Beta. I just now (11pm EDT March 11) took a look with my 20x60 IS binos and it looks like it should. If it were brighter by a LOT it would certainly be naked eye, probably similar to Mizar and Alcor...but that companion is very dim...especially that close to Alpha. On the other hand, there is decent evidence that a couple of the ancients have seen at least one of Jupiter's moons naked eye! I think if something peculiar were going on...it would be in the astro-news by now? Tom Dey
