A lucky few in Southeast Arizona will be able to see how an asteroid can hide a star tonight.
SpaceWeather.com says "Early Wednesday morning, the faint asteroid 332 Siri will occult (hide) a 6.4-magnitude star east of Antares for up to 4 seconds as seen along a track from Oklahoma across northwest Texas, southern New Mexico, and southern Arizona. The star is an unusually bright one to be occulted by an asteroid."
The event will take place low in the sky around 2:43 AM (Wednesday) over extreme Southeast Arizona.
