Cannibalistic Solar Storm:what it is and what are the consequences for the Earth

The event is so intense that it can give rise to polar auroras at low latitudes

ROME – One 'cannibalistic' solar storm is preparing to hit the Earth today, December 1st.This is an event so intense that it can give rise to to polar lights even at our latitudes, as happened last November 5th.In detail, according to what was declared by the National Oceanic and Atmospheric Administration (NOAA), the geomagnetic storm could reach G3 class (the classification scale reaches up to G5), therefore a strong intensity.

THE CANNIBAL SOLAR STORM

The coronal mass ejections (CME) they are powerful jets of material emitted from the Sun in the form of plasma and hurled into space with varying speeds up to 2000 kilometers per second.

The CME headed towards Earth today it left the Sun on November 29 during one powerful solar flare class M9.8.But she's not the only one.This strong ejection of plasma will merge with several slower CMEs, which left the Sun one day earlier (November 28), creating a single, powerful 'Cannibalistic CME'.

NOAA classifies geomagnetic storms on a scale that goes from G1, which can cause an increase in auroral activity around the poles, up to G5. This is the most extreme level:when CMEs of this magnitude occur, the consequences on Earth they are not limited to auroras.A G5 class, in fact, can be harmful both to electronic equipment and to astronauts or passengers on high-altitude planes.
