Perigee ("super") Full Moon March 10, 2020.

Full Moon March 10 22:00 AEDST, 6 hours after Perigee. Click to embiggen.Full Moon November 1 02:00, apogee -20h.

Tuesday March10 is a perigee full Moon. Strictly Full Moon is at 4:18 ACDST and perigee is at 17:00 ACDST. The Full Moon is a perigee Moon when the Full Moon is closest to the Earth. This is not as good as the April 8 perigee Moon but is still very good.

As perigee is when the moon is blow the horizon, at moon rise the Moon is receding from Earth but still larger ten at the moment of full Moon at around 4 am.

However, don't look just at moon rise as the horizon illusion will make the Moon look bigger than it is, wait until it is a decent way above the horizon. anywhere between  9 am to 11 am the Moon will still be a decent diameter. The location of the Moon to the north-east will be obvious.

You won't see much of a difference if you compare it with them memory of last months full Moon. You will need to either remember the apogee Moon of September 13/14 or wait until the October 31/November 1 apogee Moon for the best size contrast.

A full Moon at perigee has been called a "Super Moon", this is not an astronomical term (the astronomical term is perigee syzygy, but that doesn't trip off the tongue so nicely), but an astrological one first coined in 1979 (see here).

Still, it is a good excuse to get people out and looking at the Moon. A guide to photographing the Perigee Full Moon is here.
