		Moon Dog and Mars over the Atlantic Ocean. The moon was full and 10� high when Martin Turner of Putnam Valley, New York captured this image on 6th June 2001 at Montauk Point, Long Island. Mars is to the right of the moon. The moon dog is brightly coloured but lunar halos usually appear colourless to the naked eye because their light is too dim to activate its colour receptors. Look for moon halos when it is near to full.Image �2001 MartinTurner, used with permission The photograph shows the moon dog below the moon! This is purely a projection effect of the camera lens as the simulation shows. Parhelia are always at the same altitude as the sun or moon.
