Observed NLCs last night (June 28-29th) from 00.35 - 03.00 BST. They appeared as two seperate components. One in the N and the second in the NE. The NE section was a very long thin golden band with irregular edges on top however the N section was a spectacular type 5 brightness vivid golden bar jutting up from a dark stratus cloud bank at a sharp angle. This bar had a very sharp eastern edge with a thin shadow cast against a faint veil background. Within minutes it became irregular with strange loop like apendages. The bar itself seemed to unravell with delicate structure much like a magazine rolled trightly and left to open slowly. Extending to the W of this structure was faint white bands and possible unknown structure. The two components stretched 60 degrees in azimuth and 6 degrees high. When the clouds broke again before dawn I could only see a faint white mass of bands below Capella 15 degrees above the horizon. The entire display had faded rapidly and had peaked when I seen it earlier in the night. A very unusual looking display! My 20th sighting of 2007.
