Comments:
Nothern light is strange subject in Holland especially if it is possible to see at 10km from a big city (amsterdam); the area had almmost zero lightpollution. Due to freezecool a clean air and the moon at his smallest part and no clouds, only by the ground a beginning of mist: bright to see lots of pulses. some light cirkels, and sometimes as if it were huge falling stars.. The activity of the nothern light was heavy, very heavy; activy at parts in the sky from 15 to 90 elevation At the heaviest moment of the light even colorchanges to red, green, light blue signalled i am not very familiar to your method of messurement ; and i can not tell if i have seen a Zenith, arc or glows because i dont know what that means (sorry)
