X-Class Flare Released Yesterday + EIT Event

In addition to an X-class flare released yesterday by sunspot region 2035, a rare event called EIT occurred which was accompanied by a CME (coronal mass ejection). When you view the photo and video below, you will gleam such an event may not be too friendly.

Before I go with information about this EIT, it is important to note the 4.8 mag. quake which hit off the coast of Oregon around 3 PM (Pacific). It too, sits right on top of the Cascadia Subduction Zone. In this area, mantle plumes have become more active which at times releases magma and is no doubt related to this region of unstable fissures and fault lines. More on this in Monday's update laying out the science behind my assertion of a solar/lunar eclipse and escalation in earthquake-volcano- and extreme weather outcomes.

EIT waves were originally discovered by the EIT telescope (Extreme Ultraviolet Imaging Telescope) on board the SOHO satellite as propagating wave-like fronts, with an emission enhancement ranging from 25% to less than 14%, which is followed immediately by expanding EIT dimmings.

Their propagating velocity ranges from 170km/s to 350 km/s. With higher time cadence, the Extreme Ultra Violet Imager (EUVI) on board the STEREO satellite showed that the EIT wave velocity can be as small as 10 km/s and as high as 475 km/s. 

When the large-scale magnetic configuration is simple, with only one active sunspot region visible on disk, the EIT wave push produces an almost circular front. However, when there are other active regions surrounding the source region of the eruption, the EIT waves appear in patches, managing their ways outward while avoiding active regions. It is found that they stop near the boundary of coronal holes.

The discovery of such an unexpected and spectacular wave sparked a lot of interests as well as debates among the community. The modelings of EIT waves are important in the sense that they may provide crucial clues for the understanding of CMEs, they may be used to diagnose the coronal magnetic topology, and they can be used in coronal seismology to diagnose the magnetic field.
