SOLAR FLARES: New sunspot AR1532 is crackling with M-class solar flares,
including a brief but intense M6-flare on July 28th. So far none of
the eruptions has been Earth-directed, but this could change in the days
ahead as the active region turns toward our planet. Check http://spaceweather.com for updates.
