Solar activity is up. Average sunspot numbers were 13 points above the average for the previous week, and solar flux averaged about 3 points higher. Could this signal the upturn in activity we have been waiting for?
Solar flux should drift down toward about 70 over the next few days, and remain there until after the first week in December, when it should crawl up to the mid-seventies again. No stormy periods are forecast over the next 30 days, but of course this is based on previous solar rotations, and cannot predict any new coronal holes on the Sun.
Here are some path projections for the CQ Worldwide DX contest this weekend:
>From the East coast of the USA:
To Western Europe, check 80 meters from 2030z to 0930z, 40 meters from 1830z to 2300z and from 0330z to 0730z, and 20 meters from 1400z to 1730z. To South Africa check 80 from 2130z to 0400z, 40 meters from 2030z to 0430z, 20 meters from 1300z to 1830z, and 15 meters from 1430z to 1730z, particularly around 1600z. To South America check 80 from 2300z to 0900z, 40 from 2200z to 1000z, 20 from 1400z to 2100z and 15 from 1600z to 1800z.
