Full moon height

  1. Jul 2, 2007 #1
    Hi all,

    I've just read that the last full moon (29/6) was noted as the moon was lowest in the year. So there can be the full-moon when the moon can be the highest. Is that around Sep23 (equinox) or Dec22 (solstice)?

    It would be at the winter soltice. When the Sun is high in the sky the Moon is low in the sky and vice-versa.

    So it doesnt have anything to do with the tilt of the moon orbit againt the earth orbit around the sun?

    That accounts for 5 degrees of it, but the tilt of Earth's axis with respect to Earth's orbital plane (the ecliptic) has a lot more effect as it is 23.5 degrees. And that 5 degrees from the difference in orbital planes is not dependent on the solstices or equinoxes, as the direction it points (longitude of ascending node +-90 degrees) has an 18.2 year cycle that is completely independent of Earth's seasons.
