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
NASA’s Solar Dynamics Observatory captured this image of an M6.5 class flare at 3:16 am EDT on April 11, 2013. This image shows a combination of light in wavelengths of 131 and 171 Angstroms. Image © NASA/SDO
This time lapse shows what happened during four hours over Östersund here in Sweden, on Mars 17, when an CME (Coronal Mass Ejection) hit Earths magnetic field, resulting this stunning Aurora Borealis. Have a look at the video…
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 three. Watch the video…
This image of magnetic loops (like flux ropes) on the sun, captured by NASA’s Solar Dynamics Observatory (SDO). It has been processed to highlight the edges of each loop to make the structure more clear. Image © NASA/Goddard Space Flight Center/SDO
A long filament of solar material that had been hovering in the Sun’s atmosphere, the corona, erupted out into space. The coronal mass ejection, or CME, traveled at over 900 miles per second, held on August 31, 2012 at 4:36 p.m. EDT. Watch the video
Solar maximum or solar max is a normal period of greatest solar activity in the 11 year solar cycle of the Sun. During solar maximum, large numbers of sunspots appear. Solar maximum is still a year away. Images credit: NASA

The Coronal Mass Ejections (CME) unleashed by active region 1429 initially hit Earth producing amazing displays of aurora like the one shown above over Iceland, photographed by Jónína Óskarsdóttir!
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.
