The May 2010 CQ magazine has an easy to read article on sunspots. The sun plays such an important part in our on air activities. I sometimes do not pay enough attention to the sun and how it effects band conditions.
The write up also mentions NASA's new Solar Dynamics Observatory, that I posted a video of previously. Future photos and videos from the $858 million SDO satellite should be must see type of stuff.
CQ magazine is a nice simply down to earth easy read that the beginner can understand. I just wish they would put more kids on the cover, might help generate a younger crowd to the hobby.
