Explanation:
So far, the Aurora Borealis or   
Northern   
Lights have made some   
remarkable visits to   
September's skies.   
   
The reason, of course, is the   
not-so-quiet Sun.   
   
In particular, a large solar active region now crossing   
the Sun's disk has produced   
multiple, intense flares and a large coronal mass ejection   
(CME) that   
triggered wide spread auroral activity just last weekend.   
   
This   
colorful example   
of spectacular curtains of aurora   
was captured with a fish-eye lens in skies over Quebec, Canada   
on September 11.   
   
Also featured is the   
planet Mars, the brightest   
object above and left center.   
   
Seen near Mars (just below and to the right) is the tightly knit   
Pleiades star cluster.   
   
Although they can appear to be quite close,   
the northern lights actually originate at extreme altitudes,   
100 kilometers or so above the Earth's surface.
