SOLAR ACTIVITY PICKS UP: Following a week of quiet, solar activity is
picking up again with a series of M-class solar flares off the sun's
northeastern limb. So far none of the eruptions has been
Earth-directed. This could change, however, with the approach of an
active farside sunspot that appears set to turn toward our planet in the
days ahead. Check http://spaceweather.com for movies and forecasts.
SOLAR FLARE ALERTS: Would you like a call when solar flares are underway? X-flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
