Noctilucent Clouds above Averbode

Last night I walked outside and saw low above the northern horizon Noctilucent clouds. They were very bright but unfortunately very low above my horizon; which is blocked by trees and houses. Still the contrast with other clouds was clearly vissible. When finally getting my camera, the clouds were almost gone. Below some pictures of those "last" moments with low above the horizon the NLC's.
Observation was done after UT 23h30 and pictures taken around UT 23h45. Camera setting up to 6s on ISO1600.
