I saw “Steve” about 11:30 pm May 19 when I glanced out a window, even though some lights were still on in the house, so it must have been quite bright, and may have faded a bit by the time I ran through bush to get to a viewpoint. The vertical photos were 10 secs at iso 3200, 14mm f2.8 on a Nikon D7000 (apsc sensor). To my eye it was pale white with a hint of blue, oriented ESE, directly overhead to WNW, which these always have been when I have seen them here a few times in the past few decades. The motion towards the horizon was slow enough that the 10 sec exposures didn’t blur it much, but overhead (second photo) it was dramatic, with fine fingers almost at right angles to “Steve” moving very fast E to W, quite finely detailed at times. I would have needed perhaps 1/100 shutter speed to show detail, they moved the length of the Dipper in two seconds (top centre). The north side (green side) of the fingers moved faster than the south side, so that they appeared to be turning as they went over me. Shortly after the horizontal photo was taken (20 secs) “Steve” became very faint.

Beautifull!! Look like filaments. Seen that in other Steve pics as well. Birkland currents?

Thank you! Birkeland currents is an intriguing idea, especially with me standing directly below Steve with my mouth gaping open! A fellow Robson Valley resident, Robert Frear just told me he saw Steve in 1962, while driving a 1957 Buick around the valley close to midnight in the Lamming Mills area. It was straight along the valley he recalls, and it lasted at least 15 minutes. This alignment is similar to every time I have seen it on this part of the planet. The valley runs SE to NW. A clarification: in my last sentence 20 secs refers to the photos exposure. Steve got fainter over coming minutes.
