August 17-21, 2001 Aurora Gallery

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.
