Aurora over Maine


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

Aurora Borealis on March 2013

Aurora Borealis

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…

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…

Magnetic Loops on the Sun

Magnetic Loops on the Sun

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

Magnificent CME Erupts on the Sun

Magnificent CME Erupts on the Sun

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

A Taste of Solar Maximum (video)

A Taste of Solar Maximum

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

Spectacular aurora from high activity on the Sun

Spectacular aurora from high activity on the Sun

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!

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.
