In addition, Coronal mass ejections from the Sun are highly dangerous, and are fatal within a very short timescale to humans unless they are protected by massive shielding.

Coronal mass ejections have been tracked as far out in the solar system as Saturn.

The first detection of a Coronal mass ejection ( CME ) as such was made on December 1, 1971 by R. Tousey of the US Naval Research Laboratory using OSO 7.

Coronal mass ejections and their associated shock waves are also important drivers of space weather as they can compress the magnetosphere and trigger geomagnetic storms.

It can be assumed that a massive Coronal mass ejection ( CME ), associated with the flare, was launched from the Sun and reached the Earth within eighteen hours — a trip that normally takes three to four days.

Coronal mass ejections are often associated with other forms of solar activity, most notably solar flares, but a causal relationship has not been established.

Coronal mass ejections release huge quantities of matter and electromagnetic radiation into space above the sun's surface, either near the corona ( sometimes called a solar prominence ) or farther into the planet system or beyond ( interplanetary CME ).

Coronal mass ejections are usually observed with a white-light coronagraph.

Coronal mass ejections, along with solar flares of other origin, can disrupt radio transmissions and cause damage to satellites and electrical transmission line facilities, resulting in potentially massive and long-lasting power outages.

Coronal mass ejections reach velocities between to with an average speed of, based on SOHO / LASCO measurements between 1996 and 2003.

Coronal mass ejections are often associated with other forms of solar activity, most notably:

His main interest has been solar physics research, and he was instigator of the first multi-observatory observation of coronal mass ejections, joint leader at the 81. 5 MHz radio array at Cambridge, principal scientists for the first mm observations of the Sun and principal investigator of the Coronal Diagnostic Spectrometer on SOHO.

Coronal loops may have lifetimes in the order of seconds ( in the case of flare events ), minutes, hours or days.

Among his best-known early works are the illustrations he produced for The Book of British Ballads ( 1842 ), and a frontispiece he designed for The Kentish Coronal ( 1840 ).

Coronal sections divide the forebrain from rostral ( front ) to caudal ( back ), forming a series orthogonal ( transverse ) to the local bent axis.

The Coronal, Pontifex, Lady of the Isle ( of Sleep ), and King of Dreams are all humans as are the bulk of their respective staffs.

Coronal loops are the basic structures of the magnetic solar corona.

Coronal loops are highly radiating sources of plasma and therefore easy to observe by instruments such as TRACE ; they are highly observable laboratories to study phenomena such as solar oscillations, wave activity and nanoflares.

Coronal streamers are considered as sources of the slow solar wind.
