THE LIGHT SHOW CONTINUES: Geomagnetic storms are circling Earth's poles for the 2nd day in a row as a solar wind stream continues to buffet Earth's magnetic field. Today, the solar wind speed has quickened to more than 700 km/s, re-energizing storms that began on March 27th when Earth made first contact with the stream. High-latitude sky watchers should remain alert for auroras. Solar flare activity is increasing as two new sunspots are emerging on the sun today. This development comes on the heels of more than two weeks with no sunspots at all. Suddenly, the sun's X-ray output is rising as the new spots crackle with C-class explosions. Stay tuned for updates.
