Sunspots and 10m - Thurs Aug 20th 2015

Sunspot number is 36 today, marginally up on yesterday (K=3) and 10m propagation is yet again expected to remain "poor". The consensus seems to be that this has been a below average Es season too. Roll on the autumn and winter and (I hope) some decent 10m F2 propagation.  At the moment we are seeing a gradual decline, on average, in sunspot numbers but I think 10m will still be useful for one more autumn/winter period before life gets tough on 10m. The moral is never give up. I am sure 10m remains open far more often than people realise. How often have you heard 27MHz CB humming yet the 28MHz (10m) amateur band is quiet?

UPDATE 0945z:  A promising start on 10m Es today with a couple of spots by IU1DZZ (973km) quite early on 10m WSPR. On 6m WSPR I am exchanging WSPR spots yet again with G0OQK (98km) but no Es seen yet on 6m WSPR.

UPDATE 1312z:   ON7KB (299km) presumably by tropo is the only non-G spotted on 6m WSPR. I have seen no evidence of Es on 6m today and, so far, just IU1DZZ on 10m.

UPDATE 1855z:  We seem to be in "in-between" conditions at the moment with fewer Es openings and not that many F2 openings on 10m. As for 6m, there was zero Es evident here on WSPR today.
