AZI (°) (at least): ~ 300° - > 090°;
most time good to very good visibility, in the morning a lot of high Cirrus from ~S/SSE moving to N/NNW

start of display in NNE up to obvious NE at least, but more weak with height in NNE approx. 12° - 14°; later good to NW as well but best in the morning in far NE - E (at least 090° - then end for me because of house edge) with a good "3" in brightness;
NLC still visible at end of observation
