A coronal mass ejection (CME) that billowed away from the Sun on May 22nd
is heading toward Earth. The expanding cloud could trigger a geomagnetic
storm at middle latitudes when it arrives on Thursday, May 23rd or (more
likely) Friday, May 24th.  Sky watchers should remain alert for auroras on
both nights.  Our planet will also encounter a solar wind stream flowing
from a coronal hole during the days ahead.  Solar wind gusts could stir up
additional geomagnetic activity.  Stay tuned to spaceweather.com for
updates.
