Are Sunspots Disappearing?
Interesting article at science@nasa regarding speculation of future sunspots
activity or should I say the lack of activity. Whatever happens, notes Hathaway, "the sun is behaving in an interesting way and I believe we're about to learn something new." http://science.nasa.gov/headlines/y2...p_sunspots.htm -- Peter VK6YSF http://members.optushome.com.au/vk6ysf/vk6ysf/main.htm |

Yesterday afternoon, I graphed the amount of natural light striking my property. I started around 3:00 and measured until 8:00. The trend was alarming! The natural light kept getting lower and lower. If that trend has continued, there would have been no natural light at all by today. Fortunately, the light started increasing again just after sunrise this morning. Wow. That was close. (Sorry, I couldn't resist.) |

Whatever happens, notes Hathaway, "the sun is behaving in an interesting way and I believe we're about to learn something new." http://science.nasa.gov/headlines/y2...p_sunspots.htm It is not new: "If sunspots do go away, it wouldn't be the first time. In the 17th century, the sun plunged into a 70-year period of spotlessness known as the Maunder Minimum that still baffles scientists. The sunspot drought began in 1645 and lasted until 1715; during that time, some of the best astronomers in history (e.g., Cassini) monitored the sun and failed to count more than a few dozen sunspots per year, compared to the usual thousands."
