There was a continous aurora bow (I guess it was the aurora oval itself)
in the north - from NW to NE - around 18:30 on Feb 11th !
The top was about 30 degrees above the horizon.
Some brighter patches we visible below the bow occationally.
Also I glimped some aurora-looking light extending from our suburban
sodium light dome in the east.

Position 30 km NW of Stockholm. 59d29'N 17d49'E
