CME impact expected, G3 storm watch
What a day yesterday. The spectacular X1.0 solar flare (which is the second strongest solar flare of the current Solar Cycle thus far) launched a magnificent coronal mass ejection into space. Sunspot region 2887 was in a perfect earth-facing position at the time of the eruption and it was no secret that the cloud of solar plasma would have an earth-directed component. What could we expect for the coming Halloween weekend? Stay tuned!
