[NCDXA] K3ZO: SFI BEING REPORTED AT 252

[Frank W3LPL]

Hi Fred, 

The Penticton solar flux index is measured every day at 2000Z. 
Solar flare activity just before 2000Z contaminated the measurement. 
The 2300Z Penticton solar flux index was 134.

I find it hard to believe that the SFI was able to jump so much from one three-hour period to the next. However I don't see any discussion of this sudden increase on propagation websites thus far. 

I was in the YO DX Contest and the Brazilian CVA Contest last night and today. I found a curious lack of front-to-back ratio on 40 meter signals last night on my 40 meter beam, as though signals were arriving at an angle so high that the beam's ability to handle them in a normal fashion was diminished. 

As for the CVA Contest during the day Sunday, I found that absorption on 20 and 15 meters was so high toward Brazil that I kept on returning to 10 meters again and again. Ten became the band that just kept on giving. 

Interesting times... 

73, Fred, K3ZO
