Waiting for a star to flare
A star about 3,000 light years away is normally very dim--requiring a telescope and a dark sky to see. About 80 years ago, it flared up to easy naked eye visibility. Some astronomers think it might be about to flare up again.
Also, the moon is about to pass in front of one of the stars in Virgo. The event will be visible from most of a continent.
