Have a look at some of these images picked the other week from satellites which provide birds-eye views of Ireland from directly over Castlebar.
Castlebar at the centre of things of course! - from Greenland to North Africa from mid-Atlantic to Finland
Closer up at about 4 pm - it was still reasonably bright in Castlebar but the lights are on further to the East.
Castlebar from way up there! - You can see lights on in the USA to the West where the sun hasn't risen yet.
