According to Science Alert, we could be seeing a strong solar storm as well as some mild ones in the next few days.
SpaceWeather.com experts echo these claims and think that a solar storm could hit Earth today, August 18.
Forecasters from the National Oceanic and Atmospheric Administration (NOAA) warn that strong G3-class geomagnetic storms are possible on August 18 and 19, when a series of solar flares called coronal mass ejection or CME (for its acronym in English), brush against the Earth’s magnetic field.
During such storms, naked-eye auroras can descend over the United States, toward Illinois and Oregon (50 degree geomagnetic latitude). However, satellites and power grids will not be affected. An extreme storm would be required for that.
This massive ejection of particles from the Sun travels through space and the Earth uses its magnetic field to protect us from it.
Every solar storm that hits Earth is classified according to its severity and the one that could hit today has been classified as class G3. This means that there is a possibility of light displays in some US states.
A G3 class storm can also cause low frequency radio navigation problems and some high-frequency radio communications may intermittently go out.
Stronger storms may be capable of causing false alarms to be triggered by power system protection devices.
In 1989, a strong solar flare shot so many electrically charged particles at Earth that the Canadian province of Quebec was without power for nine hours.
In addition to causing problems for our technology on Earth, they can be deadly to an astronaut if they cause injury or interfere with mission control communications.
The Sun has begun one of its 11-year solar cycles, generating increasingly intense and extreme flares.
