Russian scientists warn of powerful solar flare activity on Monday

(Reuters) – Powerful solar flare activity is forecast for Monday which may interfere with short-wave communications, Russian scientists said after three flares were observed on the sun on Sunday.

The Fedorov Institute of Applied Geophysics in Moscow said class X flares were possible, including proton flares, and short-wave radio conditions were expected to deteriorate.

X-class flares are the largest explosions in the solar systems and can create long-lasting radiation storms. Proton flares are a storm of solar energetic particles, composed chiefly of proton.

Solar flares happen when the powerful magnetic fields in and around the sun reconnect. They can affect Earth’s magnetic field with the potential to damage satellites and communications equipment, according to NASA.

In 2022, a geomagnetic storm triggered by a large burst of radiation from the sun knocked out 40 then newly launched SpaceX satellites.

Three solar flares were observed on Sunday, the Fedorov Institute said, with one lasting 14 minutes, accompanied by disruption in radio communication.

Frequently Asked Questions

What is a solar flare?
A solar flare is a sudden eruption of intense high-energy radiation from the sun's surface, often associated with sunspots and magnetic field interactions.
What are X-class flares?
X-class flares are the most powerful type of solar flares, capable of causing significant disruptions to radio communications and satellite operations.
What are proton flares?
Proton flares are bursts of solar energetic particles, primarily protons, which can pose risks to astronauts and satellites in space.
What is a geomagnetic storm?
A geomagnetic storm is a temporary disturbance of Earth's magnetosphere caused by solar wind and solar flares, which can affect technology on Earth.
