Having made it's "last gasp" solar flare on the 28th November, AR1618 has finally arrived on Earth, and the following comments from SpaceWeather.com just shows you how strong that solar episode was. If the solar activity had happened during the R5 period of the 22nd - 23rd November as Piers Corbyn had forecast, there may not have been any major floods going on in the South of the UK (alas we will never know for sure if that would have been the case)..
Spaceweather.com..THE SCALE OF AMAZING: A slow but dense solar wind stream is buffeting Earth's magnetic field, igniting bright auroras around parts of the Arctic Circle. "Wow!" says Fredrik Broms of Kvaløya, Norway. "On the scale of amazing, the sky went from 0 to 100 in only five minutes." He took this picture on Dec. 1st:
"The sky has been clear for several days without a trace of any auroras here in the north, but tonight all this changed in an instant," he adds. "I witnessed one of the most powerful coronas in a long while with an exceptionally distinct band of purple-pink from excited nitrogen molecules at the lower edge. A wonderful start of December!"
