Howdy,
http://news.discovery.com/space/impact-coronal-mass-ejection-hits-earth.html
We have just been hit by CME (coronal mass ejection). I wonder if anybody
noticed :-). Any kind of strange phenomenon, like interruptions in power
and signal transmission? Auroras don't count, they are always out there,
more or less.
"August 2010 Coronal mass ejections
On August 1, 2010, scientists at the Harvard-Smithsonian Center for
Astrophysics (CfA), using images taken from NASA's Solar Dynamics
Observatory, observed a series of four large CMEs emanating from the
Earth-facing hemisphere. At an observed velocity varying between 670,560
m/s and 1,118,000 m/s (meters per second), they were expected to strike
the Earth's geomagnetic field sometime between August 4 and early August
5. As of 05:00 UTC August 4, the estimated time of arrival of the series
was as follows:
Wednesday, August 4 07:00 UTC
Wednesday, August 4 17:00 UTC
Thursday, August 5 00:00 UTC
Thursday, August 5 06:00 UTC[8]
All four were described as large and, according to scientists, possessed
enough energy to cause aurorae to be observed by the naked eye in
non-polar regions.[9] According to reports, aurorae would be visible at
night toward the northern horizon in temperate latitudes between 45° to
50°, and near overhead in regions farther north.[10]""
