A Spectacular Solar Flare Fire Plume & New Bright Regions | Space Weather News 10.18.2020
Our Sun is definitely waking up with eye-candy to boot! We went from a spotless Sun just last week to multiple bright regions on the Earth-facing disk, including two sunspots in Earth view (and possibly another if you count the big region on the Sun’s farside). These regions have not only boosted the solar flux into the mid-70s, but they are also firing off B and C-class solar flares. One of these flares, which occurred just slightly behind the Sun’s west limb resulted in the most spectacular fire plume we have seen yet in this new cycle. Likely this flare was larger than we saw at Earth because the Sun partially blocked it from view.Even at a C5-level, it still gave us a gorgeous show. Aurora photographers will appreciate the fact we have a coronal hole that will rotate into the Earth-strike zone later this week. This will begin an extended period of fast solar wind from several coronal holes, including a polar coronal hole we have seen before. Last month the fast solar wind from these coronal holes brought us up to G2-storm levels. We will see if this will be a repeat performance. If so, we expect the peak of the storm to be sometime around October 25. Finally, the farside of the Sun is almost as dazzling as the front side. We have a stunning filament bridge dangling over a big bright region on the Sun’s east limb in STEREO’s view. It is hard to tell if this filament can hang on until it rotates into Earth view before about these active regions, how radio propagation and GPS reception is faring with all this new activity, and see what else our Sun has in store!
