THE LIGHT SHOW BEGINS: As predicted, Earth is entering a stream of high-speed solar wind on Jan 18th. This morning in Alaska, first contact with the stream produced a bright outburst of auroras. Sacha Layos sends this picture from the outskirts of Fairbanks:
"Temperatures dipped down to -45F, but that didn't stop us diehards from going out anyway," says Layos. "The auroras came out to play for the first time in over a week!"
The solar wind is flowing from a large hole in the sun's atmosphere. It's a broad stream that should influence our planet for the next two to three days. Arctic sky watchers can expect continued episodes of bright auroras in the nights ahead. Free: Aurora Alerts
