    Hello astronomy fans. The Moon is due to occult Antares tonight for much of North America.

    I don't know if we'll be able to see it because of the weather, but if we do catch a lucky break, try to observe it. The only chance most of us have to observe Antares B is when the Moon occults Antares. Antares B is Antares 5th magnitude companion, but since the primary is so bright we rarely see it. It is described as a "greenish" star, but it appeared white to me when I saw it.

    I caught the occultation of Antares in March of 2005 and witnessed Antares B for about 5 or 6 seconds before the primary reappeared. It's a pretty cool thing to see.
