An activity that happens every eleven years. Astronomers call it solar max. The best place to follow the fireworks is at spaceweather dot com. The site has the latest photos including this weeks monster sunsport. It's the size of 13 Earths side by side, the largest sunspot in the last ten years.
Sunspots cause coronal mass ejections, otherwise known as solar flares.
They hurl billion-ton clouds of electrified magnetic gas right toward earth. When it hits our magnetic field you get dazzling northern lights. The solar activity has been so intense, that sky watchers have seen light shows as far as south as Houston and the fireworks are far from over. The sun may continue to act up for another year before it begins to quiet down. Of course, you should never look at the sun with the naked eye, which is why these web sites are so great.
