| Primary & Secondary Moonbow A single moonbow is a rarity, a primary and a secondary bow more so. The faint and broad secondary is at upper right. Seen by Stuart Reynolds overlooking Teignmouth, Devon, UK. The moon was within 14 hours of full. ©Stuart Reynolds, shown with permission |
| Moonbows are usually so faint that, although coloured like an ordinary daylight bow, they appear grey to our eyes The bow is too faint to excite our colour vision. Similarly, a moonlit landscape is more or less monochromatic, colours are sometimes suggested by the brain when it 'knows' that particular objects - like trees and grass - have particular colours. This enhanced version of the image shows that to the more sensitive eye of the camera all the daylight colours are still present. |
