I don't think it's a sundog. It's a long straight pillar, and it's definitely blue-hued.

It's not a sun pillar, either, as it is offset from the sun.

I think it's a fixed, vertically oriented spotlight a couple miles away, perhaps just for the purpose of creating that glow (maybe something promotional?)

Hello. Yes, great combined photo. Has anyone else noticed the vertical column of blue light from the middle (bottom) of the photo on the horizon? If so, can anyone shed light on what the nature of the blue light column is due to? Thanks!

Great Photo. I am most happy with the confirmation that it is possible to see the external fuel tank separately from the STS. I remember once seeing the STS (I think it was 120 or 121) 20 minutes after the launch and there were two white doted, which took me a while to understand but I quickly understand that it was the separated external fuel tank which fall into the Indian Ocean which fitted my position (Israel).
The external fuel tank is not as bright as the STS so it reflects less light but it was visible none-the less and it appears a little after the STS and in a quite different Orbit since it was losing speed and height preparing into its fall some several minutes later.
