Description:  The 2013 VK9CZ DXpedition to the Cocos (Keeling) Islands made 
51 QSOs with US Zone 5 on 80m. 21 of these QSOs - more than 40 percent - 
were with stations in Florida. This presentation discusses several possible 
propagation mechanisms for this grayline event, and concludes that 
propagation through the dark ionosphere, rather than along the grayline 
itself, was the responsible mechanism.
