Solar activity remains very low with only B-Class X-Ray activity detected mostly around Sunspot 1450 and region 1451. The leader spot located within 1450 did show some growth over the past 24 hours. There will be a chance for C-Class flares. 11 years ago on Monday, one of the strongest solar flares ever recorded took place around legendary Sunspot 9393. The event measured X20 and sparked a strong radiation storm around Earth. The massive Sunspot was rotating towards the western limb, so much of the expanding CME cloud was directed away from Earth.
