It looks as though the sun is finally waking, since the start of 2010 (this is written on Feb 11th), we have had a grand total of 2 days without a spot being recorded on the face of the sun, this is a distinct improvement on 2009 where there were 76% of days throughout the year without any spots at all.
Of more interest however is the sunspot number, this is still consistantly below the number forecasted by NASA. In fact Solar Cycle 24 is still shaping up to be one of the quietest cycles of modern times, and that’s if you take the definition of modern back 100 years. Cysle 23 was one of the longest recorded, as 13.4 years, while cycle 24 looks as though it’s going to be a low powered cycle that may also be a long cycle. Many radio amateurs will be hoping for a bit more than what we’ve seen so far, as the 10M band has, as far as I’m aware, not been open since the end of cycle 23
