A second CME is more likely to hit Earth on Saturday and Sunday, related to the photo voltaic flare which is rated X9.
Which means “enhanced auroral visibility is feasible additional south throughout central England and comparable latitudes, although cloud and rain may hamper viewing potential for some,” says Krista Hammond.
Within the US, aurora is likely to be seen within the northern states, and from the mid-west to Oregon, based on NOAA’s Area Climate Prediction Centre.
The X9 photo voltaic flare emitted is the biggest categorised by Nasa. The smallest is B, adopted by C, M, and X. The size ranks from 1 to 9, so X9 is essentially the most highly effective in Nasa’s rating.
