Sunspots and 10m - Sunday June 7th 2015

With the sunspot number now back at 129 (K=2) and 10m propagation expected to be "fair" we are in a battle between summertime 10m conditions (some Es and some N-S F2) and rising sunspots. Even though conditions are notionally somewhat better it would be naive to expect decent 10m propagation to suddenly return. I suspect we will have one more decent autumn and winter on 10m before we start to head firmly downwards in the solar cycle. Conditions have been pretty good on 10m overall. All I urge is for people to stick with 10m WSPR as conditions dive downwards as this will be when WSPR will prove so valuable.

UPDATE 1322z:  Some European Es on 10m but no evidence here of F2 as yet.]

UPDATE 1334z:  Just the usual suspects exchanging 6m WSPR spots inter-G. No sign, here at least, of any 6m Es or F2. So far this season, 6m has been disappointing regarding WSPR Es.

UPDATE 1618z:  10m Es at lunchtime but only G4IKZ (18km) since then and only GDX on 6m WSPR all day.  No Es on 6m so far today.

  1. Hi Roger, I have received several spots today from MW0CVT on 6m, which at 172KM is not bad. I also received 1 spot from Munich, so a small amount of ES, plus some Tropo.
