If anyone's awake in Scotland look to the north for a fantastic
noctilucent
cloud display. Sky goes from deep dark blue abruptly to strong bright pale
blue clouds. At the boundary are very clear wave formations, these may be
presence/absence of cloud waves but it may well be that the wave peaks are
just high enough to catch the sun and the troughs are not.

Will post photo links soon

Sorry for blurred images, had to try to hold the camera steady for 8
seconds. Must get a tripod...
