It's a always a treat to see a rainbow, but often there's more to see than a colorful arc in the sky opposite the Sun or Moon. If you're lucky and, of course, make an effort to look up and study the sky a bit, you might be able to observe a rainbow wheel (click on photo for a close up view). This attention-getting optical feat requires a double rainbow with anticrepuscular rays forming the spokes, while the primary and secondary bows form the rims. The bow above was the second of two rainbows that appeared on May 23, 2005 over southern Ohio. In addition, at one point a twinned bow formed from spherical and oval drops -- a real rainbow celebration.
