Sunspot Activity Reaches 95-Year Low

In June, Pound360 blogged about how the sun was strangely "dead" due to a slowdown in typical activity: spots, flares or eruptions. Well, things got really dead in August. According to a report at Daily Tech (via SlashDot), data from the Mount Wilson Observatory (UCLA) shows zero sunspot activity in August (actually, there was a "tiny speck" detected Aug 21). The last time this happened was 1913 (they've been collecting data on sunset activity since 1749, by the way).

Over the past 1000 years, "three previous such events… have all led to rapid cooling." Does this support those who don't believe humans are causing climate change? Not really. For the most part, "the effect of sunspots on TSI (total solar irradiance) is negligible." However, if anything, it would cool the earth as "reduction in the solar magnetosphere affects cloud formation here on Earth."

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
