- these are glowing lights in the circum polar skies (Aurora Borealis in the
north and Aurora Australis in the south) which result from high energy
protons ejected from the sun interacting with atoms and molecules in the
earth's upper atmosphere under the influence of earth's magnetic fields
which directs them towards the poles.
- these jets tend to reach earth some 21 hours after being ejected from the
sun in a coronal mass
ejection (CME) which is related to sunspot
activity, and cause geomagnetic activity and
storms and resultant aurorae.
- a good example of the extent of prominent aurorae is the image taken by
satellite showing the x17.2 flare from 28t Oct 2003 creating aurorae over
the nocturnal north American skies
