    Wink New Moon Spotting

    Seen below are photographs I took of four New Moons this year. I use the term New Moon in the traditional sense referring to the first sighting of the Moon after conjunction with the Sun – not the more modern usage related to the moment of conjunction. For the latter I prefer the older term Dark Moon and employ it for the monthly wallpaper calendars on my website: http://www.curtrenz.com/astronomical.html

    Notice how the positioning of the Moon changes as the months progress. That’s due to the changing geometry of the ecliptic at sunset. For a similar reason, the first sighting of the New Moon becomes later as we move from spring toward autumn.

    All four photos were taken from Arlington Heights, IL with my Sony Cyber-shot DSC-F717 at full 5x zoom. There were originally 2560x1920 pixels but cropped and reduced to 640x480.

    Very nice pics. Thanks for posting!

    Your photo with the Earthshine - we call that the "old Moon in the New Moon's arms."
