Hi folks,
I hope this comes out okay. I took this photo this morning with my cell phone just prior to descending through the clouds north of Baltimore on our way to Ronald Reagan George Washington National Airport. This light phenomenon is called a "glory", and to make it easy I'll just paste a quote in from Wikipedia.
Glory (optical phenomenon)
From Wikipedia, the free encyclopedia
A glory is an optical phenomenon produced by light backscattered (a combination of diffraction, reflection and refraction) towards its source by a cloud of uniformly-sized water droplets. A glory has multiple colored rings. The angular size is much smaller than a rainbow (http://en.wikipedia.org/wiki/Rainbow), about 5° to 20°, depending on the size of the droplets. Since it is seen in the direction opposite the sun, it is most commonly observed while airborne, with the glory surrounding the airplane's shadow on clouds (this is often called The Glory of the Pilot). The phenomenon is also known as an anthelion (http://en.wikipedia.org/wiki/Anthelion).
Their pictures are better than mine, but you can easily see a glory when the sun is behind you and you are descending through a cloud layer. then the shadow of the airplane will be in the middle of the colored rings.
look for it the next time you fly. :eek:
