Earth could be hit by solar storm caused by opening of a “hole” in the Sun

The Sun is in its 25th cycle and when it started, researchers warned that this new 11-year period would not be as calm as the last one that ended in late 2019. Some events, such as the solar flare of the M4 class. 4, or as an X-class explosion, which occurred in 2021, show the current activity on our star. A new alert warns that a solar storm could be about to hit Earth as material flows out of a hole in the Sun.

According to information from the National Oceanic and Atmospheric Administration (NOAA), Earth is expected to be affected by a G1-class solar storm.

The G1-class storm could cause radio communication problems, disrupt satellites and disrupt animal migrations. These events, fortunately, happen less frequently. However, they produce possibly much more dramatic effects during geomagnetic storms.

According to NOAAsuch conditions are "likely" today Wednesday, August 3as a result of a hole in our star.

As we learned, coronal holes appear as dark spots in images of the star when taken using ultraviolet and X-rays. They are the coldest, least dense parts of our star, which means the solar wind is more easily able to escape. to space.

This means that fast currents of solar wind can be thrown out of the Sun - and can be directed towards Earth. This collision of the solar wind with the Earth's atmosphere will produce a light effect that will glimpse our atmosphere, leading to potential effects both in space immediately above us and on Earth.

Sun has holes that can be a threat

Coronal holes can form at any time, although they happen most often during the time of solar minimum. Now, it is exactly from this solar minimum that we are heading towards the solar maximum, where the activity of the Sun increases in intensity, which is expected to arrive around 2025.

As this time approaches, scientists expect space weather to have a more regular and potentially more harmful impact on life on Earth. Scientists have repeatedly warned that human civilization should do more to protect against the damage caused by solar weather before more intense events arrive.

NOAA's scale for solar weather starts at G1, as is expected to be Wednesday's storm, which is referred to as "minor".

The scale goes all the way to the G5 - an "extreme" geomagnetic storm - where widespread problems in the energy system are expected, spacecraft could be disoriented and radio and satellite navigation signals could be temporarily wiped out.

Such extreme solar storms are, however, relatively rare. Extreme solar storms of this type only about four days occur in each of the Sun's 11-year cycles.
