X-ray flux at GOES-16 has been nearly flat for the last 20 minutes, still at X1.3 allowing R3 (Strong) radio blackout conditions to persist across the northern and central Atlantic basin and surrounding regions, including eastern North America, northern South America, most of Greenland, northwestern Africa, and western Europe. #solarflare#spaceweather#spacewx
It's worth noting that AR3697 is the return of our old friend AR3664, which was responsible for numerous X-class flares and the strongest geomagnetic storm in over 20 years during its previous transit. #solarflare#spaceweather#spacewx
After a whole day and a half with no significant solar activity, newly-designated AR3685 — currently the largest active sunspot region on the visible disk as it rounds the east limb — just produced an M7.2 X-ray flare (R2 – Moderate radio blackout). This is on top of the X2.9 flare it produced while it was still on the far side of the limb, suggesting that its transit across the disk will be a busy one. #solarflare#spaceweather#spacewx
