~Space Weather Update~ Chance of Storms Today Continued M Class Flares WOOHOO

CHANCE OF STORMS TODAY: NOAA forecasters estimate a 45% chance of polar geomagnetic storms on Feb. 2nd in response to a glancing blow from a CME. High-latitude sky watchers should be alert for auroras on Super Bowl Sunday. Aurora alerts: text, voice
BIG SUNSPOTS FACE EARTH: A pair of large sunspots is directly facing Earth. The larger of the two, AR1967, has a 'delta-class' magnetic field that harbors energy for powerful solar flares. NASA's Solar Dynamics Observatory photographed the behemoth during the early hours of Feb. 2nd:
AR1967 is wider than the planet Jupiter and its primary dark cores are big enough to swallow Earth many times over. The scale of the sunspot makes it an easy target for backyard solar telescopes. As shown in the gallery, astronomers around the world are snapping pictures.
The active region is already crackling with M-class solar flares. NOAA forecasters estimate a 15% chance of even stronger X-flares during the next 24 hours. Any eruptions will be squarely Earth directed. Solar flare alerts: text, voice
