Car
headlight fogbow by Michael Ellestad (atmospheric
optics site). The shadows of the camera and tripod are visible
on the track. The camera shadow marks the centre of the bow. The main
fogbow is fringed with red on the outside. Inside it a well defined
supernumerary has reversed colours - blue outside and red inside.
Look outside the main bow to see a faint secondary fogbow produced
by two internal reflections inside the fog droplets. More car
fogbows. ©2004
