sun wind

Solar Wind is known as a phenomenon characterized by the emission of gas which is made up of a series of particles that have an electrical charge, mainly from the nuclei of hydrogen atoms with a high energy charge which can reach 100 keV, furthermore they also include nuclei of helium atoms as well as electrons. These ions are produced in the solar corona, a surface that can exceed two million degrees Celsius, in those places where the magnetic field is a little weaker. An important fact is that the particles can reach speeds that range between 350 and 800 km per second; For its part, in the vicinity of the Earth’s orbit, it has an approximate density of 5 units per cubic centimeter.

This is considered an astronomical phenomenon, it is produced in the form of cycles, which is called a cycle of solar activity, has an approximate duration of about eleven years and is controlled by the sun’s magnetic fields, in which they alternate times of great solar activity with those in which it is less active both in frequency and intensity.

Those particles that make up the solar wind are capable of traveling through space at speeds that reach 450 kilometers per second, for that reason it has the ability to reach the earth in a period of 3 to 5 days. This phenomenon is transmitted in space as a shock wave that can reach the surface of the different planets and even extend beyond the limits of our solar system, accompanying the sun’s magnetic field and also a significant amount of matter on its surface.

The existence of a continuous flow of particles that are expelled towards the exterior of the Sun, was a hypothesis suggested by the British astronomer Richard C. Carrington. Later, in 1859, Carrington and Richard Hodgson independently observed for the first time what would later be called a solar flare. Said phenomenon refers to a sudden burst of energy from the solar atmosphere, a day after such an event a geomagnetic storm was observed and Carrington assumed that there was a connection between the two.
