THE FUTURE OF SOLAR ACTIVITY Ssome good news and some bad news for those who follow the Suns activity so as to know when the best time to work DX. It comes from the folks whose job it is to predict the Suns future. Graham Kemp, VK4BB, has the details:
NASA Scientists predict that Solar cycle 24 will be the best ever with solar activity the highest ever experienced but cycle 25 which should peak around 2022 is expected to be the worst ever for radio propagation. The reason for this is a slowing of the Sun`s Great Conveyor Belt, a massive circulating current of hot plasma inside the Sun. The belt has two branches, in the north and south which normally move at about 1 metre per second. This means each belt completes a circuit in approximately 40 years. Researches believe that the turning of this Conveyor Belt controls the sunspot cycle. Recent measurements indicate that both the northern and southern branches of the belt have slowed to a crawl. This slowdown will affect future sunspot cycles, with cycle 25, peaking around the year 2022, predicted to be less than half the strength of Cycle 23. Cycle 24 however, is predicted is to be one of the strongest sunspot cycles since the 1960`s. A full explana ion of the Conveyor Belt can be found on the NASA website at http://science.nasa.gov/headlines/y2006/10may_longrange.htm While 2022 might seem a long way off for some, remember that this is 2006 and so that really bad cycle is only sixteen years away.
