WAVES OF IONIZATION - Space Weather

[Sowelu]

 

WAVES OF IONIZATION: Waves of ionization are rippling through Earth's upper atmosphere in response to the recent onslaught of solar flares. This affects the propagation of radio signals--suppressing some frequencies and boosting others. By monitoring distant transmitters at a frequency of 23.4 kHz, Rudolf Slosiar of Bojnice, Slovakia detected nearly a dozen sudden ionospheric disturbances (SIDs) on Feb. 18th:

"Each surge in signal strength corresponds to a specific solar flare," notes Slosiar. "Individual peaks exactly match events recorded by Earth-orbiting satellites."

More waves of ionization are iin the offing as sunspot complex 1161-1162 continues to crackle with M-class solar flares. The next SID could be over your backyard. Do-it-yourself SID monitors are available from Stanford University.
