SOLAR WIND STREAM
ENTERING THE SOLAR WIND STREAM: As
predicted, today Earth is entering a stream of high-speed solar wind.
First contact with the gaseous material sparked bright green auroras
over Iceland. "We saw them through gaps in some nice lenticular clouds,"
reports Olivier Staiger, who sends this picture from the Fjallsarlon
glacier lagoon:
"The auroras were nice and bright and wide--mostly green with a fringe of pink," says Saiger.
The solar wind stream responsible for this display may be here for a while. Flowing from a large hole
in the sun's atmosphere, the stream is broad and should take several
days to cross. Arctic auroras are possible from now until at least
