NOAA expects a geomagnetic storm of level G1 on Tuesday, and level G2 on Wednesday
Geomagnetic storms are disturbances in the Earth’s magnetic field
They can have impacts on communications, on satellites or on the migration of some animals
–
From the Space Weather Prediction Center of NOAA (National Oceanic and Atmospheric Administration) a geomagnetic storm G1 and G2 level after a powerful ‘solar flare‘. It is not ruled out that this event could have an impact on communications and affect terrestrial satellites, experts warn.

Geomagnetic storms are disturbances in the Earth’s magnetic field that can produce spectacular northern lights at latitudes lower than usual, in addition to affecting communications on the surface, “they wreak havoc on geomagnetic systems and pose a danger to satellite operations”, Indicate from NOAA.

Magma ejections from the Sun or CME
These storms are caused by what is known as CME, which stands for ‘coronal mass ejection’, or what is the same, a expulsion of plasma and magnetic field of the solar corona. Solar winds sometimes move these CMEs towards Earth at high speed, impacting the magnetic field.

Those of type G1, like the one expected for this Tuesday, the 25th, they are smaller. They can cause fluctuations in the electrical network, in satellite operations and even affect some animals during migration.
–
Those of type G2, of moderate level –more intense than the G1–, such as the one that will take place on Wednesday 26th, they generate vibrant northern lights. But, “while storms create beautiful auroras, they can also disrupt navigation systems such as the Global Navigation Satellite System (GNSS) and create harmful geomagnetic induced currents (GIC) in the electrical network and pipes,” they warn from the NOAA.

During the most severe geomagnetic storms, levels G3 and G4, problems in radionavigation may be experienced and corrective actions on spacecraft may be necessary.
