BIG SUNSPOTS FACE EARTH: Potential Spaceweather

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.

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..

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.

This composite image taken on Saturday with a DMK51 through my 127ED and baader solar wedge, it comprises of 14 images (600 frames per video) to make the white light mosaic. That sunspot group AR11967 (aka AR11944) is massive - several earth diameters.
