Seems to be a very impressive eruption indeed Mark, i was checking the sferics charts about half hour ago for the showers coming into the west coast of Ireland and noticed the lightning plots over Iceland. They line up perfectly with the satellite image of the ash cloud. Cheers Mark, keep us updated!
There is alot of lightning being produced in this ash cloud
