Brenda Osborn spotted these crepuscular rays from the deck of the boat she shares with her husband Bob Osborn (Member 54,749). They were in Falmouth Harbor, Antigua, the Caribbean. Crepuscular rays like these can appear when clouds cast shadows onto other clouds, creating beams of light and shade. In this case, a gap in the tall Cumulus clouds off on the western horizon allowed light from the low evening Sun to shine up onto the underside of Altocumulus clouds above Brenda. A small fragment of Cumulus, known as Cumulus fractus, cast its own shadow in the middle, splitting the beam into a V shape.
