... followed by an ASTOUNDING display in the dawn twilight, probably at its best about 0345 BST when it filled well over half of the sky, with a sharp edge parallel with the NW horizon at 45 degree elevation below which the cloud was absent - there was a bright patch in the south east at 25 degrees elevation, very bright ripples & glow in the north east passing right over the zenith fading gradually into "normal twilight" high in the south west. Didn't pay much attention till after 0330 as I was trying to observe Jupiter; I didn't bother trying to image the NLC as it would have been impossible to do it justice without a 180 degree fisheye camera.
