coronal mass ejections: Five Solar Eruptions in 2 Days!

Solar Filament Eruption Sends CME Towards Earth
Full disk view of magnetic solar filament erupting during the early hours of February 24, 2012. A coronal mass ejections (CME) directed toward Earth accompanied the filament eruption. This video was taken by the Solar Dynamic Observatory in extreme ultraviolet wavelength (304 angstrom).

Five Solar Eruptions in 2 Days – CME On the Way

From February 23 through February 24 our sun produced an astonishing five solar
eruptions, launched from the top, bottom, left and right sides of the solar
disk. Four of those eruptions came in just a 24 hour period.

One of the
eruptions, a large snaking magnetic filament, erupted during the early hours of
February 24, 2012 and launched the first of two coronal mass ejections (CME) in
Earth’s direction. Analysis by scientist at the Goddard Space Weather Lab shows
that this CME cloud will strike Earth's magnetic field on February 26, 2012 near
8:30am EST (+/- 7 hr). Geomagnetic storms and aurora are possible when the CME

The filament eruption, as seen in the video above taken by the Solar Dynamic
Observatory (SDO) in extreme ultraviolet wavelength, forms a visible split in
the sun's atmosphere, where plasma races away in waves in opposite directions.
The divide stretches the length of the original filament location, almost
248,500 miles (400,000 km).

Solar filaments are darker, cooler solar
material floating above the sun's surface, suspended by magnetic forces. When
they appear over the solar limb they are called prominences.
