Now, for the first time, scientists have been able to follow coronal mass ejections
from inside the sun's atmosphere all the way to Earth's orbit.
Coronal mass ejections
- CMEs to avid sky watchers - are rated for intensity on an A to Z scale, with A being the weakest and Z being the most intense.
But scientists at the National Oceanic and Atmospheric Administration in Boulder, Colorado, said they had observed another, much bigger coronal mass ejection
It was later observed to erupt, producing a spectacular coronal mass ejection
moving away from the Sun at a velocity of nearly 600 km [s.sup.-1] (see www.youtube.com /watch?v=tXwQ46FEB_s).
Dr Li added: "We don't yet know what causes these coronal mass ejections
and that is really what we hope to discover."
Scenario: New York, 3:30 pro, May 14, 2013--A withering mass of material ejected from the surface of the sun, what scientists call a coronal mass ejection
, occurred three days previously.
The solar eruption, or coronal mass ejection
, was spotted by the sun observation spacecraft Soho yesterday.
Don't be surprised to hear: "A coronal mass ejection
is likely to shake Earth's magnetic field this week.
An active region just about squarely facing Earth erupted with an X 1.6 flare (largest class) as well as a coronal mass ejection
The eruption, known as a coronal mass ejection
(CME), has led to a "massive amount of solar particles heading towards Earth", which are due to pass the planet this morning, a spokesman for the Met Office said.
Well, if the Government are looking for a really nasty scenario, then how about universal cooling coupled with a global pandemic, and a coronal mass ejection
(CME) with these events occurring roughly all at the same time, and that is something to be frightened about!
Recently coronal mass ejection
(CME) and solar energetic particles (SEPs) have received a significant amount of study, thanks the peculiarities of solar cycle 23 and to new orbiting and ground-based systems.
