Dear Colleagues: 
     On behalf of the IES2008 steering committee, and the Special Session Conveners, Dr. Anthea Coster and Dr. Alessandro Cerruti, we are pleased to announce a special session at IES2008 dealing with the Impact of Solar Radio Bursts and Solar Flares. A short description follows. The published abstract deadline is 1 February 2008. IES2008 is to be held in Alexandria VA on May 13-15, 2008. A flyer is attached in PDF form. 
 
The Impact of Radio Solar Bursts and Solar Flares on Technological Systems: Chaired by Dr. Anthea Coster (Haystack-MIT) and Dr. Alessandro Cerruti (Cornell Univ.) 

This topic recognizes that solar radio bursts, solar flares, and  environmental noise can impact telecommunication and navigation systems. Solar flares can produce sudden ionospheric disturbances (SIDs) as the Earth’s ionosphere reacts to the intense X-ray and ultraviolet radiation. SIDs can interrupt or interfere with telecommunication systems. System performance typically depends upon signal-to-noise ratios (SNR), and systematic, man-made, and environmental noise are major factors in the determination of how well a radio wave system may perform. Solar radio bursts have been shown to have a measurable impact upon the GPS system, and recent studies of an historical solar radio burst in December 2006 (circa 2006 and following) have confirmed that severe performance degradation occurs. Further examination of these effects would be of interest. Studies of the effects of solar flares and of man-made noise, galactic noise, atmospheric noise, and cosmic noise bursts are welcome.
