#CME' SPARKS #AURORAS OVER #ICELAND: Every day the sun hurls multiple CMEs into space. Many are faint; some overlap; they go in all directions. It's inevitable that space weather forecasters lose track of some of them. On Sept. 26th, one of those "lost CMEs" hit Earth, sparking this display over Iceland:

"Lying on the ground, looking directly up and seeing the auroras right above me was just incredible!" says photographer Wil Cheung.

No one knows where the instigating CME came from.
