Sunspot AR1967 is Back, and it Just Produced an X-Class Flare
Just to remind us of its capabilities it has thrown off an X-class 4.9 flare.
Usually sunspots fade away when they move off the Earth facing side of the Sun, degrading and disappearing at some point on the farside. Not so with sunspot AR1944. After a transit across the far side of the Sun it reappeared, and was redesignated as AR1967. Incredibly it’s back for the third time…and still active.
It will be redesignated today or tomorrow, having just popped into view on the far south eastern edge of the Sun disc. Just to remind us of its capabilities, it has thrown off an X-class 4.9 flare. The Coronal Mass ejection that followed the flare will miss Earth due to the position of the sunspot.
It’s incredible that this spot still has the energy to produce flares at all, let alone X-class flares.
We have escaped the wrath of this very active region twice already, lets hope that the adage third time lucky holds true.
Todays sunspot number is 205. NOAA estimates the chance of further flares today at 60% for an M-class and 10% for an X-class.
