In NASA failed to provide data on the size of the prominence, but the resulting images called terrible. The information on the website of the agency noted that the value of some of the prominences can be up to 600 thousand kilometers. These scales can for example be compared with the diameter of the Earth, which is only 13 thousand kilometers.
IA REGNUM reminiscent, on Sunday began on Earth magnetic storm caused by the appearance of solar activity. According to scientists, the magnetic disturbances Class G1, weaknesses could be due to the surge in solar activity, which happened on September 18.

prominences – cooled plasma ejected from the outer layers of the Sun, then it is held through a magnetic field stars.
The study of this phenomenon began July 8, 1842 the year when there was an eclipse of the sun. Astronomers Erie, Arago and others then noticed a strange bright pink ridges around the black disc of the Earth satellite.
There is a special classification of prominences in appearance, features of motion of matter inside and speed. Thus, isolated quiet prominences. When the substance is moving slowly, the existence of can be weeks to months, form too slow to change.
When active substance flows prominences are moving pretty fast, time – up to several days. Eruptive prominences appearance resemble huge fountains, which reach heights of up to 1.7 million kilometers above the surface of the Sun, they are short on time. Coronal and loop appear above the chromosphere in the form of small clouds and there are a few hours.
