Northern Lights 'ash green'
A series of spectacular images of the Northern Lights have been captured over the ash plume from the Iceland Volcano.
The incredible images show in amazing detail the sky lit up in amazing green colour above the Eyjafjallajökull volcano.
In the images, captured by New York-based photographer Lucas Jackson, red lava can also be seen spewing from the top of the active volcano.
Mr Jackson had earlier captured an astonishing lightning display over the volcano, which he wrote about in detail in an online blog.
The images, from the Reuters news agency, came as Iceland said it would close two of its airports for the first time later on Friday just as the rest of Europe was starting to recover from a week of airline chaos caused by the volcanic ash cloud.
The Icelandic aviation authority has announced that the Keflavik International Airport and Reykjavík International Airport will be closed from this morning.
Airports within Iceland had previously been unscathed by the giant ash cloud thanks to strong northwest winds which blew ash from the volcano, in the south of Iceland, out to sea and over Europe.
The closures come as airports are finally reopening across Europe after world travel was crippled for almost a week.
At its peak, the crisis affected 1.2 million passengers a day and 29pc of all global aviation, according to the International Air Transport Association.
Stranded air passengers have been warned they could face a lengthy battle to reclaim the cost of hotels and meals despite budget airlines agreeing to reimburse them.
