Sunspot Cycle 24

We HF Radio aficionados wait, not so patiently, for the return of the small group of sunspots that indicated the beginning of sunspot cycle 24. The return of sunspots to our sun will mean improved HF propagation allowing long distance contacts particularly on higher frequencies such as 10 meter band.

The average sunspot number for the month of November was 6.8, up
from 5.2 for October. The three month sunspot number average ending
November 30 — centered on October was 4.5 — an increase from
August and September’s 1.1 and 2.5.

This image shows there are currently no sunspots, but beginning Dec 5, we should see the return of the small group observed previously.
