Wow: a big solar eruption

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 now say that the current solar maximum cycle will peak in late 2013, thereby relieving the stress of doomsday predictions which suggest that a breakdown of the electrical grid could cause the predicted […]

The Sun is definitely waking up

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. A positive effect of the delay in the return of sunspot activity is that the maximum period will not coincide with December 2012 as previously feared.  This was one of the explanations for the fearmongering surrounding the December 2012 date, […]

The Sun is waking up

c-flare

Solar scientists met last week to discuss the higher levels of solar activity that are likely as we move out of the Solar Minimum of the past few years.  The head of NASA’s Heliophysics Division says “our technological society has developed an unprecedented sensitivity to solar storms.” Spaceweather reports an M2-class flare on June 12th that hurled a billion-ton coronal mass ejection into space, and a new sunspot has emerged with a series of its own eruptions.   Solar flares have been connected with weather extremes, and there have been […]

A new sunspot cycle?

The current Solar Minimum cycle has had 619 days of a spot-free Sun (as compared with the typical solar minimum of 485 days).  But Spaceweather reports today that a new active region on the Sun produced a Coronal Mass Ejection and a burst of radio emissions on the far side of the Sun that probably points to a new sunspot. Increased solar activity affects satellite transmissions on Earth, and it seems to me that it likely affects the human electrical fields as well.  The next sunspot cycle is expected to peak in 2012, leading some […]
