Summary: A coronal
mass ejection
that left the Sun on August 14th struck Earth's magnetosphere
on August 17th. The interplanetary magnetic field near Earth
turned south -- a condition that renders our planet's magnetosphere
more vulnerable to solar wind gusts -- and the ensuing geomagnetic
storm lasted 12 hours. Sky watchers as far south as Sacramento,
CA, spotted Northern Lights. Then, on August 21st, Earth entered
a
solar wind stream
flowing from a coronal hole. That triggered a new round of high-latitude
auroras.

B. Alber: "At the Oregon Star Party, I photographed
faint aurora with the Big Dipper. The photo was taken on Sunday
morning August 19th at 3 am. It was shot with Fuji film, ASA
800 at f 1.4 for 2 minutes, unguided. We did not see it clearly
until we had the film developed!" |
