I saw an interesting rainbow yesterday. It actually looked like it was inverted – instead of arching down towards the earth, encircling the earth, the ends appeared to go up as if encircling something in the sky.
From what I found online, the physical explanation is that I must have seen a higher order bow, the 3rd or 4th reflections of the light within the water droplets sending the light forward and creating a bow that encircles the sun.
Keep watch my friends, for we know neither the day nor the hour.
And the one who sat there had the appearance of jasper and ruby. A rainbow that shone like an emerald encircled the throne.
