The Far Side of the Sun by Jonathan Polkest

Solar flares also create a wide spectrum of radio noise; at VHF (and under unusual conditions at HF) this noise may interfere directly with a wanted signal.The frequencey with which a radio operator experiences solar flare effects will vary with the approximately 11 year sunspot cycle more effects occour during solar maximum, when flare occuence is higfh, than during solar minimum, when flare occurence is very low, A radio operator can experience great difficulty in transmitting or receiving signals during solar flares due to more noise and differentr propagation patterns. An extremely powerful flare was emitted toward EARTH on September 1st 1859, it interupted electrical telegraph service and caused visable aurora borealis as far south as Havana, Hawaii, and Rome with similar activity in the southern hemisphere. The most powerful flare obseved by satelite instrumentation began on November 4th 2003 at 19;29 UTC and saturated instruments for 11minutes, Region 486 has been estimated to have produced an X-ray flux of X28 Holographic and visual observations indicate significant activity continued on the far side of the Sun.
