NW-part: max. 300° - 335° (right edge of automatic camera)
N-part: max. 345° (left edge of automatic camera) - 040°;
many clouds in the evening before cloud gaps with NLC became larger

*most of the time = automatic camera observations, probably brighter NLC before own visual inspection start at 21:40 UT;

no NLC seen during two checkings in the morning part whilst not optimal conditions (~ haze / contrast effects up to 10° in height)
