faint + early start with almost All-Sky-NLC:


21:00 UT, t = 1,6", ISO 2500, 8/16 mm, approx. original view, N at bottom
same image, contrast enhancement:

NLC did not became brighter, better said they faded away...

21:14 UT, t = 5", ISO 2500, 8/16 mm, (contrast enhancement)
 
 

Then came a break, waiting for widespread and light NLC...
...took some time and then they appeared more or less low above northern horizon:


21:47 UT, t = 0,4", ISO 1600, 2,2/35 mm


22:01 UT, t = 0,8", ISO 1600, 2,2/35 mm
 

Then a break again because of clouded sky conditions.

At last some single frames taken from an automatic video. Shots are from the morning hours:
