Karen C. Fox, NASA's Goddard Space Flight Center Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun’s activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space. However, the timing of the solar cycle is far from precise. Since humans began regularly recording sunspots in the 17th...

Brett Smith for redOrbit.com - Your Universe Online Our Sun is constantly cycling between periods of low activity and high activity – known as solar minimum and solar maximum, or Solar Max, respectively. In 2008 and 2009, NASA’s solar experts reported they were surprised to see the Sun descend into one of its deepest solar minimums in recorded history. But now, NASA observers are saying that the solar minimum is almost over. [ Watch the Video: ScienceCasts: Solar Mini-Max ]...

New science book looks at solar science and dissects it for an easier understanding. Mount Holly, Vt. (PRWEB) October 03, 2013 In “Grand Phases On The Sun: The case for a mechanism responsible for extended solar minima and maxima” (published by Trafford Publishing), author Steven Haywood Yaskell explains distinguished solar scientist Cornelis de Jager’s papers concerning whether or not the solar maximum for the solar cycle will be very strong or very weak. “Is there yet another...

Twin Peaks For Solar Cycle?

redOrbit Staff & Wire Reports - Your Universe Online While 2013 is supposed to be the year of Solar Max - the peak of the 11-year sunspot cycle - the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks. According to NASA, sunspot numbers during the months of January and February 2013 were well below values recorded back in 2011. Furthermore, they report that...

Hinode And SOHO Paint An Asymmetrical Picture Of The Sun

Approximately every 11 years the magnetic field on the sun reverses completely — the north magnetic pole switches to south, and vice versa. It's as if a bar magnet slowly lost its magnetic field and regained it in the opposite direction, so the positive side becomes the negative side. But, of course, the sun is not a simple bar magnet and the causes of the switch, not to mention the complex tracery of moving magnetic fields throughout the eleven-year cycle, are not easy to map out....

Researchers at Reading University said that solar storms are likely to become more disruptive to planes and spacecraft within decades. The team predicts that once the Sun shifts towards an era of lower solar activity, more hazardous radiation will reach Earth. The researchers said in Geophysical Research Letters that the Sun is currently at a grand solar maximum, which is a phase that began in the 1920s. Mike Lockwood, professor of space environment physics at Reading, said in a statement:...

American government scientists are warning users of satellite, telecommunication, and electrical equipment to be prepared for potential disruptions due to the recent occurrence of solar flares in the sun, Reuters reported on Saturday. Earlier last week, three coronal mass ejections (CMEs) were released by the sun following solar flares -- the first on August 2 and two others the following day. The initial CME arrived at Earth on August 4, around 5pm EDT, while the remaining two combined and...

A new analysis of the unusually long solar cycle that ended in 2008 suggests that one reason for the long cycle could be a stretching of the Sun's conveyor belt, a current of plasma that circulates between the Sun's equator and its poles. The results should help scientists better understand the factors controlling the timing of solar cycles and could lead to better predictions."¨"¨The study was conducted by Mausumi Dikpati, Peter Gilman, and Giuliana de Toma, all scientists in the...

An international panel of experts led by NOAA and sponsored by NASA has released a new prediction for the next solar cycle. Solar Cycle 24 will peak, they say, in May 2013 with a below-average number of sunspots. "If our prediction is correct, Solar Cycle 24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78," says panel chairman Doug Biesecker of the NOAA Space Weather Prediction Center. "Even a below-average cycle is capable of...

After two-plus years of few sunspots, even fewer solar flares, and a generally eerie calm, the sun is finally showing signs of life. "I think solar minimum is behind us," says sunspot forecaster David Hathaway of the NASA Marshall Space Flight Center. His statement is prompted by an October flurry of sunspots. "Last month we counted five sunspot groups," he says. That may not sound like much, but in a year with record-low numbers of sunspots and long stretches of utter spotlessness, five is...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
