1. Jan 01,  · Abstract: We examine how the initial state (pre-event corona) affects the numerical MHD simulation for a coronal mass ejection (CME). Earlier simulations based on a pre-event corona with a homogeneous density and temperature distribution, at the lower boundary (i.e., solar surface) have been used to analyze the role of streamer properties in determining the characteristics of loop-like transients.

2. Most coronal mass ejections (CMEs) registered in a coronagraph field of view are related to various manifestations of solar activity in the lower corona (low coronal signatures — LCSs): flares, filament eruptions, EUV waves, dimming etc. Meanwhile, there are CMEs observed by coronapraphs that are not related to LCSs.

3. Coronal mass ejections (CMEs), or bursts of plasma and magnetic field from the sun's corona, have much in common with ecarducfemalerapecengechefi.coinfo follow a cycle, albeit a far more regular one (the conditions are ripe every 11 years or so) [source: NASA].They also cause variable but potentially ruinous damage, and their destructive scales depend, in part, upon humans' connectedness.

4. e. A coronal mass ejection (CME) is a significant release of plasma and accompanying magnetic field from the solar corona. They often follow solar flares and are normally present during a solar prominence eruption. The plasma is released into the solar wind, and can be observed in coronagraph .

5. A sunspot is a dark area on the surface of the Sun that was formed by the sudden magnetic flux from the massive star’s interior. The sudden change in the magnetic field activity within a sunspot.

6. Jan 31,  · Several coronal mass ejections (CMEs) are observed by NASA's SOHO, thanks to the power of its [+] sun-blocking coronagraph that enables the dynamic corona .

7. We present a forward-modeling technique for flux rope-like CMEs using an empirically defined model of a flux rope, the graduated cylindrical shell (GCS). To compare it with white-light coronagraph observations, we assume an electron distribution through the GCS and derive synthetic images in total and polarized brightness for various projections of the model using a Thomson scattering ray.

8. Jul 29,  · Coronal mass ejections (CMEs) usually result from rapidly erupting magnetic flux ropes (MFRs). Observations from white-light coronagraphs and extreme-ultraviolet (EUV) passbands demonstrated that.

9. Oct 22,  · A coronal mass ejection from the sun could hurl radiation that destroys our power grid. So it's high time we figured out how to predict them. 73% of African Americans said they did not have.
