I suppose it must be mist, but it looks like thick grey cloud, and it's
actually quite cold. What happened to the clear blue sky we wuz
promised?

AM also feeling v miffed because I couldn't see any noctilucent cloud
last night like (it seems) everyone else could... There was a bank of
cloud in the north-east at 23h that just looked as if it was reflecting
light from the city underneath, was that it? And how can you tell,
especially in town, the difference between true noctilucent cloud and
high cloud reflecting the sun just under the horizon, or low cloud
reflecting the lights of the city?
