I just photographed weak NLC here almost to the zenith in northeastern Spain (Sant Vicenç de Castellet, 41.67N, 1.86E). I was actually looking for the area closer to the horizon when I noticed blueish patterns most pronounced at 40-60° at 3:30 UT. I photographed the most pronounced features (a large scale whirl to the NNW and small whirls higher up, NNE) and with some contrast enhancement I could bring out patterns extending beyond them that were invisible to the eye. The display faded after 3:45 UT. The brightness was 2 for the main features. Stay tuned for photographs.
