Sunspots and 10m - Mon April 25th 2016

Solar flux is just 82 today although the sunspot number has risen to 46 (K=2). The forecast for 10m propagation (F2) remains "poor", although Es might bring some life to the band.

We can already see the progression down the solar cycle. Next year will be much tougher by F2 on 10m. Luckily Es tends to be good in spring and summer whatever the state of the solar cycle, so we can depend on this mode on 10m, 6m and 4m. Es openings on Band II (VHF FM radio) and 2m are much rarer. They do occur but catching an Es opening on the higher bands is far less common than on 10m and 6m. May, June, July and August will see 10m and 6m open by Es almost daily.

UPDATE 1012z:  No spots given or received yet on 6m or 10m WSPR.
