entering the solar wind

ENTERING THE SOLAR WIND STREAM: Earth is entering a stream of fast-moving solar wind flowing from a large hole in the sun's atmosphere. This is causing the Arctic Circle to glow with green auroras--a hue that could intensify as our planet moves deeper into the stream on Jan. 19th.  NOAA forecasters estimate a 60% chance of G1-class geomagnetic storms during the next 24 hours.
