Spring officially begins!
An extremely rare event will take place shortly after 2 a.m. EDT on Thursday, March 20. An asteroid known as 163 Erigone will pass in front of the bright star Regulus in the constellation of Leo, causing the star to disappear. A stellar occultation (pronounced “occ-kull-tay-shun”) occurs when the Moon, an asteroid or another planetary body eclipses a star, momentarily blocking its light. This event will be visible along a 45-mile-wide path and is predicted to begin at 2:07 a.m. Eastern Daylight Time. The asteroid’s shadow will move on a southeast-to-northwest path that will extend from New York City to Oswego in New York State and continue northwest into Ontario, Canada. For those in the center of this path, the star will remain invisible for 12 seconds.
