General Discussion Area / Auroras this weekend?

SEVERE GEOMAGNETIC STORM WATCH: Giant sunspot AR3664 has now hurled at least four CMEs directly toward Earth. Their combined arrival this weekend could spark severe (G4-class) geomagnetic storms with mid- to low-latitude auroras. Although this is a potentially significant space weather event, it is not going to be the next Carrington Event. If the coming storm were a hurricane, it would be ranked category 4, not category 5.
Sunspot AR3664 has grown so large, it now rivals the great Carrington sunspot of 1859. Carrington's sunspot is famous because in August and Sept. 1859 it emitted a series of intense solar flares and CMEs. The resulting geomagnetic storms set fire to telegraph offices and sparked auroras from Cuba to Hawaii. The "Carrington Event" has since become a touchstone of space weather in pop culture, with recent headlines stoking fears of an "internet apocalypse" if it repeats.
