Slow Moving Solar Coronal Mass Ejection - Video

A large but relatively slow moving coronal mass ejection (CME) that erupted from the Sun on September 27 hit Earth September 30 causing a low level radio blackout and moderate geomagnetic storms.

Although the blackout has passed, storm warnings continue through October 1.

In a couple of weeks, NOAA's GOES-15 satellite, which is the primary X-ray solar sensor used to monitor solar weather, will undergo a maintenance phase as its view of the sun is eclipsed by Earth.

During that time NOAA's GOES-14 will be brought online to provide continuous coverage of solar activity.

GOES-15 is expected to be operational again around October 30.
