Dying comet 73P/Schwassmann-Wachmann 3 continues to break apart. Astronomers are tracking at least 20 fragments approaching Earth for a harmless but beautiful close encounter in May.

In particular, fragment B of the comet has brightened 15-fold since April 2nd. This signals a possible breakup of “73P-B” into even more fragments. Amateur astronomers with backyard telescopes and CCD cameras can monitor the ongoing disintegration. Visit Spaceweather.com for sky maps, images more information.
