SOLAR WIND ARRIVES EARLY: Arriving a day earlier than expected, a stream of fast-moving solar wind is buffeting Earth's magnetic field today. The broad stream is expected to influence our planet for the next three days with a 60% chance of polar geomagnetic storms between now and March 23rd. Arctic sky watchers should be alert for auroras in the waxing Spring twilight. Visit Spaceweather.com for more information and updates.
