Thanks to Astrococktail for this link to a NASA article on the Solar Minimum, the expected period of low sunspot activity. The Solar Minimum came right on schedule back in 2006, as I reported in this earlier article. But this Solar Minimum is setting all kinds of records.
In 2008 the Sun was completely blank of sunspots 73% of the […]
Beginning in February of this year, the Sun has been completely blank with no sunspots. NASA solar physicist David Hathaway says “Solar minimum has arrived.” In 2004, he predicted that solar minimum, a period of low sunspot activity, would arrive in late 2006 and it appears it […]
It seems pretty much everyone agrees now that the earth is warming, and the extreme weather over the past week certainly seems to confirm that both the weather AND the climate is changing. Steven Forrest’s July newsletter included an article about the current Solar Maximum which reminded me that I […]
Cosmic Ray Origin still mysterious
I don’t know much about cosmic rays, but I do love it when science can’t explain everything. Cosmic Rays are a bombardment of tiny electrical particles to earth from deep space and scientists recently discovered that the supernova explosions or gamma ray bursts which formerly were […]
http://youtu.be/KsSqCN57fAM The sun has been very active over the past few years; as I wrote in August 2010 the prolonged “solar minimum” period meant that the maximum period which follows would be delayed somewhat beyond the predicted 2012 date. Solar cycles tend to last anywhere between 9 and 14 years, but they average about 11 years. Most astronomers […]
After a prolonged “solar minimum,” with record long periods without sunspots, the Sun has become extremely active again. These periods of solar maximum alternating with solar minimum are a normal part of solar activity but the last solar minimum was particularly long: 12.4 years rather than the usual 11 years.
