The most dramatic effects of the impacting plasma clouds, from active sunspots are auroras. Earlier this month active sunspot region 2158 rotated into view and unleashed a series of flares and plasma ejections into the Solar System.   Image © Jeremy P. Gray

Fiery Looping Rain on the Sun

Fiery Looping Rain on the Sun

Eruptive events on the Sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material (called a coronal mass ejection – CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the Sun’s atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all threeWatch the video…

Solar Storm toward Earth on 5 March

Solar Storm toward Earth on 5 March

A solar flare seen by the joint ESA/NASA SOHO mission, which reached its peak at about 04:13 UT on 5 March 2012. The flare caused a Coronal Mass Ejection (CME), which was ejected toward Earth.
