A Powerful Geomagnetic Storm on Nov. 24th Triggers Northern Lights
A Powerful Geomagnetic Storm on Nov. 24th Triggers Northern Lights
24 Nov 2001

Did you see strange lights in the sky before dawn on Saturday? If so, you were probably watching an outbreak of auroras. A pair of fast-moving coronal mass ejections, arriving somewhat earlier than expected, buffeted Earth's magnetic field on Nov. 24th at 0530 UT (12:30 a.m. EST). The resulting geomagnetic storm spawned Northern Lights as far south as Arkansas in the United States.

Although the ongoing storm will probably subside during the hours ahead, high-latitude sky watchers (including those along the northern tier of US states) should remain alert for auroras Saturday night and Sunday morning. Visit for updates.
