I sent a message to geoscience Aust. and even though this phenomenom was outside of there observational brief I was sent a couple of links which after clicking to afew other links from that one led to to this one:
http://www.global-vision.org/ireland...oon/index.html
which after staring aimlessly at it for about half an hour started to make some sense.
Apparently the moons precessional cycle moves in an 18.6 year cycle much quicker than the earth's. Anyway at the time of major standstill the moons descending and ascending nodes, where it crosses the ecliptic on its way south and then 2 weeks(approx) later north, coincide with a spring/vernal equinox the moon's full 5 degree inclination to Earth adds and then subtracts the the Earth's 23.5 degree to its inclination to the ecliptic thus bringing about the very high southern position at one point in the cycle and the very low northern in the same lunar month. The moon rises very gradually further to the west each night. until this cycle then repeats
Now at this stage I only think I understand this
so check it for yourself and if you can make more sense please let me know.
