Sunspots and 10m - Mon April 27th 2015

With a sunspot number of 55 (K=1) and a 10m propagation forecast of "poor" I guess we cannot expect great things on 10m today?  It is surprising though how often I am proved wrong and a "dead" 10m band just springs into life. So far this morning, just local G4IKZ (18km) has spotted me on 10m WSPR, but it is still very early.

Of course, a SN of 55 will be considered "high" in a few years' time. We should be grateful. With the Es season now here there is an increasing chance of Europeans (and further) by this mode too. Es is there at all times of the year but it is best late April- September in northern latitudes, the reverse in Australia/NZ.
