These were actually from over the weekend (same night as that photo of my parents on the GW, a couple of posts back). Both photos were shot facing almost straight south, from mid-span of the GW Bridge. I thought it was cool that there was such a distinct band of orange even on the horizon opposite of the sunset. I suppose that it was caused by the particulate matter in the air. Who knows? All I can say is that, I thought it was nice-looking enough to snap a few and post ‘em.
