A very bright region appears at the center of the sun. An explosion from this region propels material into space.

The #sun is on fire! In just 24 hours, sunspot AR4366 — 10x wider than Earth — erupted with 5 X-class #flares, including an X8.1, the 3rd-largest of Solar Cycle 25. Strong #radioblackouts hit Earth’s sunlit side, and space weather watchers are on high alert. Read more:

The new #SpaceWeatherWoman forecast is up! Learn about the network of filaments creating major solar eye candy this week. See how fast #RadioBlackouts will rise, & find out why #aurora photographers smile while radio operators & GPS users frown: www.patreon.com/posts/137150...

Our Sun gets busy! Big flare action from Region 4114 continues, causing increased risk for #RadioBlackouts and #RadiationStorms. A wide coronal hole brings extended fast solar wind & #aurora views through this week. Region 4105 launches some gorgeous eye candy near the west limb!

Here is your #SpaceWeather Snapshot ahead of my new forecast out tomorrow: An Earth-directed #solarstorm expected to hit Earth June 12-13. Also, new regions are rotating into view that will raise noise on the dayside radio bands & increase the risk for #RadioBlackouts and flares this week.

Fast #solar wind continues throughout this week. Strong #aurora possibilities at high latitudes with sporadic shows at mid-latitudes. #RadioBlackouts on Earth's dayside at the R1-level level will continue and slowly increase. HF radio & GPS effects should be minor to moderate.

My new #SpaceWeatherWoman forecast is up. Learn the details of the #solarstorm series hitting Earth now. Watch 3 back-to-back filaments erupt in a gorgeous display, find out why #RadioBlackouts are not going away any time soon, & see what else our Sun has in store. www.patreon.com/posts/126691...
