THE SOLAR WIND HAS ARRIVED

THE SOLAR WIND HAS ARRIVED: Arriving a day earlier than expected, a stream of solar wind hit Earth's magnetic field on Jan. 27th.  This is causing intermittent G1-class geomagnetic storms and Northern Lights around the Arctic Circle. Rauno Pakarinen sends this photo from Pieksämäki in eastern Finland:
The solar wind responsible for this display is flowing from a hole in the sun's atmosphere. It is expected to influence our planet for the next 2 to 3 days, with a 40% chance of continued geomagnetic storms on Jan. 27th and Jan. 28th. Arctic sky watchers should remain alert for auroras this weekend.
