   Car headlamp fogbow II 

  Another spectacular car headlight fogbow taken the previous autumn by Marko Riikonen and Jukka Ruoskanen. This time the fog is older and has larger droplets with a wider size distribution.  The only supernumerary is narrower and closer to the primary.  ©Marko Riikonenand, shown with permission
   IRIS simulation for droplets with a mean diameter of 17 micron and a size distribution of 15% standard deviation.
