What is the origin of the solar storm that will hit Earth on Thursday?

¿Cómo se forma la tormenta solar que impactará el jueves sobre la Tierra?

The Doctor of Physics and Space Weather Tamita Skova warned a few days ago that yesterday Tuesday 19 July would hit the earth Solar storm. The pundit defined the impact of yesterday’s solar storm on the planet as “a serpentine filament,” and nets threw up their hands and rumors of major power outages in electrical, internet and communications systems came to the fore.

Skov is a researcher at la United States Aerospace Corporation and it’s known on networks like that “Space Weather Woman” and although NASA made no statement or any warning, this is what the network expert did based on one of the same space agency’s prediction models. Either aemetthe agency in charge of assessing this impact in Spain, has launched an alert on this geomagnetic storm.

However, according to forecasts Center for Space Weather Detection (NOAA), will be the Thursday 21st July when any of the solar ejections reach Earth, although they are expected to be of minor importance. In any case, the activity cycle, which normally increases every 11 years for the Sun, is increasing again, as NOAA has asserted in its most recent communication on the subject, which means that solar flares are also increasing in frequency.

But how does a solar storm form and what happens when it hits Earth?

Northern lights and disturbances in power lines

A solar or geomagnetic storm is “born” after an episode of large solar or solar wind emissions. coronal mass ejections which, depending on their intensity, can cause changes in the Earth’s magnetosphere.

That Northern lights are one of the effects of solar storms. The interaction between the particles ejected from the sun and the atmospheric molecules is concentrated at an altitude of between 35 and 750 kilometers Make the phenomenon visible and tangible.

As mentioned aemet“Auroras have a direct impact on HF communications and satellite positioning systems. They are also closely associated with ground-induced currents that can affect power lines and transformers.”

The torches coming from the star are accompanied by X-rays which in turn are usually absorbed in the first layer of the atmosphere. However, if it had enough energy to distort the ionosphere, it could disrupt the propagation of radio waves. The speed at which the particles that make up these flares travel (between 300 and 1000 kilometers per second) can cause various types of damage communication system, power distribution grids and various devices.

According to NOAA, the expected geomagnetic storm will be level 1, the lowest therefore, episodes or impacts on intensive networks are not expected.
