I took these photos (https://picasaweb.google.com/fred.prata6/NoctilucentClouds?authkey=Gv1sRgCP2378XJlYLlKw) yesterday from Kjeller (Lillestrøm), Norway at ~18:20 CET (before the sun had set). I was not sure what caused them but perhaps they are noctilucent clouds?
Welcome aboard. No these aren't NLC. For information and advice on how to identify NLC go to www.nlcnet.co.uk/ All the details are there. However your pictures are great!, what you have is some dense cirrus, possibly coming in with a jet stream on a frontal system, a nice halo and the "lens" shaped lower clouds are a form of altocumulus lenticularis. These indicate high wind speed at mid levels. Lovely shots. Cheers, Bill.
