Falling sunspots and poorer 10m conditions

Sunspot number today was 45, the lowest for a long while and 10m conditions expected to be "poor" again. The 10m band is again open to the USA. We should remember that even with a SN of 45 the 10m band can still be good to the USA. Even if the peak of sunspot cycle 25 only reaches 45, we should still expect 10m openings to the USA by F2. Of course, as mentioned before, I expect the 10m band will still be good for transatlantic DX next autumn for the CQWW DX SSB contest, but following years will be very doubtful.
