GEOMAGNETIC STORM: A G1-class geomagnetic storm is underway on April
2nd as Earth enters a fast-moving stream of solar wind. The stream is
filled with "negative polarity" magnetic fields. Such fields can easily
link to Earth's own magnetic field, opening a crack in our planet's
defenses against solar wind. This is why NOAA forecasters offer good
odds of continued magnetic storming--a 60% chance on April 2nd followed
by a 55% chance on April 3rd. High-latitude sky watchers should be
alert for auroras this weekend.
