Ah! That probably explains the sunset I saw this evening. Very deep red sky
out to the west, which isn't that unusual. However, there was also a deep
red tinge to the sky way over to east of north. I stood looking at it for a
while trying to work out why. Large gap of normal sky colour between the
two. Very unusual. East of north from here is Lincolnshire.
