CME IMPACT: A CME hit Earth's magnetic field on Nov. 26th at approximately 0500 UT (Nov. 25th @ 9 PM PST). The weak impact did not cause a geomagnetic storm. Aurora alerts: text, voice.
PRESTO! A HUGE SUNSPOT: Yesterday, sunspot AR1620 was barely visible. Today it is a behemoth wider than a half-dozen planet Earths. NASA's Solar Dynamics Observatory recorded the sunspot's rapid growth in a period of less than 20 hours on Nov. 25-26:
AR1620 has a beta-gamma magnetic field that harbors energy for strong flares. Because of the sunspot's proximty to the center of the solar disk, Earth would be in the line of fire of any eruptons. NOAA forecasters estimate a 30% chance of M-class solar flares in the next 24 hours. Solar flare alerts: text, voice.
