One of the flares was so strong it may have caused a radio blackout for about an hour over the weekend.
A NASA Solar Dynamics Observatory image shows an X-class solar flare flashing on the sun at 4:25 p.m. EDT on October 2, 2022. The flare was one of multiple to occur over that weekend.Solar flares are bright flashes of radiation that burst out from the sun's atmosphere whenever the sun's twisted magnetic field lines suddenly shift. This magnetic rearrangement releases huge amounts of energy.
Sometimes a solar flare is the first part of a two-stage eruption. A flare consists of a flash of radiation that travels towards Earth at light speed, meaning its effects are felt as soon as we notice it. Solar flares can cause disruption to high-frequency radio communication networks on Earth because these radio waves must bounce off a region of Earth's atmosphere known as the ionosphere in order to travel to their destination. Solar flare radiation ionizes the ionosphere, causing these waves to become degraded or completely absorbed.
"These types of disturbances affect the aviation and global navigation satellite systems communities in the civil dominant," George Ho, a space physicist at Johns Hopkins Applied Physics Laboratory, told."In addition, the military also relies heavily on high-frequency communication. It is reported that space weather disturbance may have caused communication blackout during Operation Anaconda.
