A CME IS COMING: Minor G1-class geomagnetic storms are possible on Jan. 19th when a CME is expected to graze Earth's magnetic field. The CME was hurled into space on Jan. 14th by a dramatic twisting eruption in the magnetic canopy of sunspot AR3182. High latitude sky watchers should be alert for auroras when the CME arrives.

CME IMPACT SPARKS AURORAS: Arriving earlier than expected, a CME struck Earth's magnetic field on Jan. 17th around 2200 UT. Its arrival was signaled by an abrupt shift in the interplanetary magnetic field (IMF) near Earth. The impact sparked a brief outburst of Arctic auroras, which has since subsided. https://www.spaceweather.com/images2023/14jan23/two_cmes.gif

CHANCE OF FLARES: NOAA forecasters say there is a 60% chance of M-class solar flares and a 15% chance of X-flares today. The most likely source is giant sunspot AR3190, which is directly facing Earth.
