A series of CMEs is heading for Earth

At least four coronal mass ejections are heading toward Earth following a series of solar eruptions on November 23rd and 24th. An S1 to S2-class solar radiation storm that began around 1500 UT on November 24 is subsiding. The storm was triggered by a series of three X2-class solar flares that exploded Friday over sunspot group 9236, near the center of the Sun's Earth-facing disk.

SOHO's Extreme Ultraviolet Telescope captured the explosions. The first interplanetary shock wave could strike Earth's magnetosphere on the November 25-26 night. Forecasters estimate a 40 per cent chance of severe geomagnetic activity at middle latitudes when the CMEs arrive. Sky watchers should be alert for auroras after sunset on Saturday and again on Sunday.
