GROWING SUNSPOT: The sun is showing signs of life. Over the weekend, sunspot 1029 emerged and it is crackling with B- and C-class solar flares. This movie from the Solar and Heliospheric Observatory (SOHO) chronicles the sunspot's rapid development from Oct. 23rd through 25th.

In Ocean Beach, California, amateur astronomer Michael Buxton made his own movie using a digital camera and backyard solar telescope:
