Solar Flares

January 22nd Fact-of-the-Day

Solar flares are incredibly powerful solar explosions that release a force equal to 100 hurricanes or so within a period of tens of minutes. The process is not fully understood, but it is believed that strong and wildly-twisted magnetic-flux that is known to exist near sunspots is the power source. Depending on the direction of a flare discharge, high-amplitude x-ray energy and ultraviolet photons may strike Earth about eight minutes later, followed by large quantities of high-energy particles several hours later. These radiations increase ionospheric ionization, increasing the absorption of signals in the lower part of the high-frequency spectrum and creating unusual DX opportunities at higher frequencies. ©2005 Martek, International.
