The sun's magnetic field will reverse its polarity three or four months from now, as it does every 11 years at the peak of the solar activity cycle. Researchers know enough about this process to predict when it will occur, but its causes remain mysterious
07 August 2013, 07:06 PM ET
The sun's magnetic field is set to reverse its polarity in the next few months. But the shift won't spark an increase in solar storms or other events that could have a damaging effect on Earth and its inhabitants, researchers say.

The sun is going to flip. In an event that occurs once every 11 years, the star's magnetic field will reverse its polarity in a matter of months, according to new research from NASA-supported observatories.
06 August 2013, 11:09 AM ET
During the height of the solar cycle, the magnetic field changes polarity, pushing a ripple effect across the Solar System that's detectable by even the far-away Voyager probes.

Over an eight hour period on July 20th 2013, a solar prominence stretched over the western limb of the Sun (as viewed from Earth). It resembled the sliding reptile during its super-heated travels.

Though the sun is at its 11-year peak of activity, our closest star has been rather quiet. This year's solar maximum is shaping up to be the weakest in 100 years - the weakest since Space Age began - and the next cycle could be even weaker.

The online Slooh Space Camera will webcast live telescope views of the massive sunspot AR1785 from Arizona today at 1 p.m. EDT (1700 GMT). The sunspot is 11 times the size of Earth and currently facing our planet, a solar flare threat.
