Six-color flags are quite common in my San Diego neighborhood of University Heights. Real rainbows are rare occurrences, and a delight, in part because rain is uncommon. Yearly average precipitation (October to September) is about 25 cm (10 inches). We are already well above that number, following a series of storms.
That explains my seeing two rainbows in the sky on consecutive days—one to the West from the front of our apartment building and the other East in the alley behind. The latter is the Featured Image, taken yesterday using Samsung Galaxy S24 Ultra.
