Astronomy: A Very Quiet Sun

From One-Minute Astronomer comes the lowdown on what's been going on with the Sun. Apparently it's having an abnormal cycle - right now it should be having loads of spots, but it's not. It means less auroras but also less interference for satellites. But it's not the first time this has happened.
