EA6VQ's 144 MHz. sporadic-E statistics

This statistics were made using the data of the sporadic-E openings worked by myself from Jan.1987 to Dec.2002. They should not be taken as an exact reference as I have missed many openings in those years.

See also the detailed statistics of 2007 and 2008

Just saw your research info on 144 MHz. sporadic-E statistics. I worked on that data many yrs ago with/for W3ZZ. All my data was shared with him. Still havent thrown it! Hi There was a European Ham that sent me his many books on yrs of data, I did QST search, my records from 1950s on up & other. Saw it in my junk collection lately & will try to find it & scan it in. BTW, I was trying to do predictions & by best was related to Coronal holes +3 days. Only abt 50% good! Dick
