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.

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.

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.

The sun fired off an M1.5-class solar flare on July 3 as an early preview to the Fourth of July fireworks, NASA officials say.
03 July 2013, 09:30 AM ET
On July 1st, 2013, a large prominence erupted off the Sun's eastern limb and on July 3rd, an M1.5-class flare made a statement. Neither eruptions were Earth-directed. NASA's Solar Dynamics Observatory snapped imagery.
