Day #36 - A peculiar sunset

I was housesitting on the far east side of town, and happened to be driving east as a big monsoon storm rolled in. The sun was setting in a blaze of color behind me, but it was nothing but grey swirling clouds to the east. Suddenly, this otherworldly spot of color flared behind the clouds. It lasted for a couple of minutes - a bizarre trick of reflection and refraction. I've never seen its like.
