STORM IN PROGRESS: A severe geomagnetic storm is in progress on Oct. 30th. It began at approximately 1700 UT when a coronal mass ejection (CME) swept past Earth. The CME (movie) was hurled toward our planet yesterday by an X10-class explosion from giant sunspot 486. Sky watchers at all latitudes should be alert for auroras.

BRIGHT AURORAS: Oct. 29th was a great day for sky watchers. A CME hit Earth's magnetic field and triggered an extreme geomagnetic storm. In the United States, Northern Lights appeared as far south as Florida, New Mexico, Arizona and Texas.
