Last night we could observe a quite impressive NLC display over the
illuminated city of Chemnitz/Germany (51 deg N, 12 deg E). Starting
our observation at around 21:00 UT we first saw bright NLC spread
over the whole NW/NE sky up to a hight of about 5 deg. There were
several distinct arcs and waves visible, that developed rapidly. At
the beginning they overspan an area of about 45 degrees at the horizon.
Later the display became smaller and fainter with the western border
of the clouds staying almost constant, whereas the eastern part disappeared
slowly. At 21:45 the was only one or two bright arcs left,
at 22:00 only one dimishing arc in the low north-west. At 22:15 even
this last clouds was gone.
I hope, we were not the only ones who observed this phenomenon. May be
there have been more NLC in the morning sky?
