Daytime Moonrise


Today at 1055 the Moon will rise at due east.  Sunlight should reflect off the edge of the Moon, which is forming a thin triangle with the Sun and the Earth.  The Earth and the Moon are like specs bound close together, rotating around the Sun which is 400x further away.  Right now the Moon is slightly in front of and beside the part of the Earth facing the Sun in its rotation, so a thin part of the bright side of the Moon is visible to Earth as a crescent.  At 1055, the Earth will have rotated enough so that Ottawa will be facing both the Sun and Moon in space.  Daytime should allow a picture!
