Poor conditions tonight with some high cloud & lumps of decaying shower cloud but NLC positive at 2330 (May 30th) - a smooth band / arc about 3 deg high in the north, less high to the west & east of north, the arc is about 2 deg in height. Very faint indication of rays from the northern horizon stretching up towards Cassiopeia but I think these are high cloud (cirrostratus) illuminated by twilight rather than auroral in nature.

Edit: Hmmm, reviewing images I'm no longer so sure ... maybe the arc is just shadowing by cirrostratus. Judge for yourself.
