Space Weather News for July 19, 2002

Another coronal mass ejection is heading for Earth.  It was hurled into
space Thursday, July 18th, by an explosion near the huge sunspot 30. The
expanding cloud could trigger geomagnetic activity when it sweeps past our
planet.  Sky watchers--especially those at high latitudes--should be alert
for possible auroras after nightfall on Friday and Saturday.

Meanwhile, sunspot 30 remains impressive. It stretches 15 Earth diameters
from end to end. A second spot (active region 36) has grown nearly as
large in recent days. You can see both--but NEVER STARE DIRECTLY AT THE
SUN.
