Moonbow and Venus imaged by Rob Ratkowski (photography) in May 2004.    Moonbows are very rare. The moon must be bright and not too high, the sky must be dark else the faint bow will not be visible and there must be rain in the direction opposite the moon.   Orion was setting when Rob took this spectacular image, Venus is the bright object inside the bow. Mars is above it to the left and Saturn is above Mars and outside the primary. Capella is the bright star to the right (north) of Venus. Do not expect to see much colour with the unaided eye because moonbows are usually too faint to excite the colour sensors in our eyes. We therefore mostly see them as a series of grey shades. ©2004 Rob Ratkowski, shown with permission.
