MINOR

STORM WARNING: On August 2nd, the sun hurled a cloud of plasma (CME)

toward Earth when magnetic fields above sunspot 1261 erupted. Analysts

expect the CME to arrive during the early hours of August 5th, possibly

sparking geomagnetic storms around the poles. This is not a big event;

the eruption that propelled the cloud in our direction registered only

" M1 " (for medium) on the Richter Scale of Flares. Nevertheless, sky

watchers at high latitudes should be alert for auroras. Movies of the

eruption and 3D models of the incoming cloud are featured on today's

edition of http://spaceweather.com.
