Move over California Chrome. After delivering three X-class flares in two days, sunspot group 2087 wins the triple crown for solar eruptions. And the fun’s not over yet.
Between it and two other spotted regions (2080, 2085) there’s a 60% chance for moderate M-class flares and 30% chance for more X-flares through Saturday. Plus, it turns out that part of the blast from 2087’s double-X flare is whooshing its way toward Earth right now.
Most of the solar plasma blasted sideways off the sun after the eruptions but not all. NOAA space weather forecasters now predict a 20-25% chance of minor auroral storming overnight tonight through Saturday. With each day that passes, region 2087 inches closes to the center of the sun, where it will face Earth more directly, improving the outlook for auroras in the wake of new flares.
