I looked out the window late afternoon and thought that looks like a sundog, burning white against the softer whites of the clouds, softly enough to look at. But I didn't think the angle of the sun was right for that. So I went to the south window.
Yes, the angle of the sun was right for a sundog. But that was only part of what I saw. A halo of light encircled the sun -- very palely. It was neither pure white nor a rainbow shade; I could make out clearly a reddish ring, and about it a more yellowish one, but there the colors stopped. And to one side, the sundog gleamed brilliantly, like the stone in a ring, reddish, then yellowish, and even a hint of green before it turned to a white so brilliant it was hard to look upon.
