Coronal_Mass_Ejection_Erupts_on_the_Sun_2012

On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3.

During the earthquake, the bay side of Gilbert and Crillon inlets moved about 20 feet northwest relative to the northeast wall that forms the head of the bay. The Sunmore (S) and Badger (B) were anchored in Anchorage Cove, while the Edrie (E) was anchored in the small cove behind the Paps hills. Map credit: Don J. Miller, Giant Waves in Lituya Bay, Alaska.
