What causes this line shooting up from the horizon? Before you start saying sunlight, the sun has already set on the opposite side. You are facing East in this photo, the sun is behind me, just set in the West. Note you can see there is no sunlight illuminating those big storm clouds on the Eastern Horizon as well, again demonstrating that the sun has already set behind me. So what is this long straight line emanating from the centre of the horizon up toward the upper right corner?
Two things to note. The contrast of this line is heavier at the horizon, which also throws a spanner into the mix. And it is not an effect from the car window.
I noticed this phenomena on Friday afternoon in Perth, Western Australia immediately as something unusual.
I saw again, it is not the sun, its already set in the West behind me, and the lack of sunlight on those storm clouds proves this.
Highly unusual.
