GEOMAGNETIC STORM: A solar wind stream hit Earth's magnetic field during the early hours of March 1st. The impact sparked a polar geomagnetic storm that was, at first, minor, but the storm has been intensifying throughout the day. If the trend continues, high-latitude sky watchers will likely witness bright auroras after nightfall on March 1-2. Northern-tier US states such as Maine, Wisconsin, Minnesota, and Washington could be favored with photographic and/or visual displays. Check http://spaceweather.com for updates.
