Rainbow Spotted

In the last 4 weeks, between a hurricane, tropical storm, stalled cold front, and persistent low pressure area, we've received about 24" of rain. That's about 6 months of rain (4" a month) in one month. Everything is soggy and we have a lot of fungus growing over everything in the region. Finally, though, we got a rainbow out of the deal this weekend.

A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth's atmosphere. It takes the form of a multicolored arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

In a so-called "primary rainbow" (the lowest, and also normally the brightest rainbow) the arc of a rainbow shows red on the outer (or upper) part of the arc, and violet on the inner section. This rainbow is caused by light being refracted then reflected once in droplets of water. In a double rainbow, a second arc may be seen above and outside the primary arc, and has the order of its colours reversed (red faces inward toward the other rainbow, in both rainbows).
