2024: From "Mini" Moons to "Super" Moons, a year of full Moons

A year of full Moons showing the variation in size as the moons move from perigee to apogee. I also show the apogee and Perigee First Quarter Moons. All the moons are shown on the day and time they are full (unless they are below the horizon, in which case the size at astronomical twilight is shown and the time of actual full moon is shown as well), and although this is not the optimal time for size comparisons, you can clearly see the size difference over the year (compare Feb 24 to Sep 18) the original scale for all is 2 degrees of field of view cropped down). Although the field rotation of the Moon makes it less clear, you can also see the effect of libration (June 22)
In 2024 we have two good Perigee Moons in a row (September 18, October 17). However, as you can see the differences are subtle, and it requires a keen eye and good memory to distinguish a perigee "super" Moon from more ordinary moons, the best contrast is with the apogee "mini" moon of February 24, even though this is not a good apogee Moon).
That doesn't mean you shouldn't try though. Daniel Fischer has been able to see the difference, you can read
his account and viewing tips here:

Photographing them can be more rewarding. You can see images of perigee Moon and apogee Moon pairs from 21 Jan 2019 here and 10 August 2014 here.Tips for photographing them are here.
There is also a penumbral Lunar Eclipse on 25 March but twilight makes this difficult to see.

Coming Events: A Year of Southern Astronomy for 2024
The table below shows significant astronomical events that can be seen with the unaided eye or minimal equipment in 2024 in Australia (and to some degree elsewhere in the Southern Hemisphere, ocultations and eclipses are very region specific).
This year we get a Penumbral Lunar eclipse best visible from eastern Australia. We get multiple occultations of Saturn (some daylight only). A couple of occultations of the Pleiades, and an occultation of the bright star Antares (only visible western and central Australia). There are good oppositions of Jupiter and Saturn. Mars is at opposition in January 2025 but we get a good run up to it. We also get a comet in September/October, C/2023 A3 Tsuchinshan-ATLAS, which may be a fizzer but just might be spectacular.
As well we have some fantastic parings and lineups and good meteor showers.
Close pairings of the Moon and bright planets are given special
attention as not only is the Moon a ready guide to locating the planets
if you are not familiar with them, these massings are rather beautiful.
Special events are bolded.
