  • welcome to

    macarthur astronomical society

  • observe

    Astronomers use scientific observation to learn about the Universe we live in. It's a beautiful place and, as a group of keen amateur astronomers, M.A.S. members have it as their common interest. We observe from two southern Sydney locations.

  • photograph

    Along with our "visual" observers, we have a group of dedicated astrophotographers within our ranks. This group find that photographing deep sky objects with high-quality cameras brings out the colour which your own eyes are unable to detect. See our photographs and you'll want to take your own.

  • educate

    Come to a Macarthur Astronomy Forum evening, held at UWS Campbelltown, to hear talks given by Australian and international professional astronomers as well as from amateurs with interests in their own specific fields. Entry is free for all.

  • events

    M.A.S. members are deeply committed to sharing our combined knowledge of, and love for, the night sky and the science of astronomy. We hold public open nights during the year - keep watching out for "What's On".

 

Macarthur Astronomical Society

Amateur Astronomers 

With over 100 financial members, we are amateur astronomy enthusiasts from right across the South Western Region of Sydney, Australia.

We conduct the Macarthur Astronomy Forum each month at the Campbelltown Campus of Western Sydney University.

We arrange  public astronomy nights in collaboration with Campbelltown Rotary Observatory at Western Sydney University; and we hold regular dark sky observing sessions for our members.

  

Lunar Eclipse 

Saturday 28th July

A total lunar eclipse will occur on the morning of 28th July, visible from Macarthur.

You will need to be awake early to view it (partial eclipse visible between 4.24 am and 5.30 am; total eclipse visible from 5.30 am to 6.57) and you will need to find a suitable location with a very clear westerly horizon view.

The Moon will be low in the sky during totality - and will still be fully eclipsed as it sinks beyond the horizon.

This is a timetable of the eclipse and twilight events:

TIME EVENT ASPECT ALTITUDE
3.13 am Penumbral eclipse begins  West 43°
4.24 am Umbral eclipse begins  West 29°
5.26 am Astronomical dawn (Sun 18º below horizon) ~ ~
5.30 am Total eclipse begins WSW  16°
5.56 am Nautical dawn (Sun 12º below horizon) ~ ~
6.21 am Mid eclipse WSW 
6.26 am Civil dawn (Sun 6º below horizon) ~ ~
6.53 am Sunrise ENE 0°
6.57 am Moon sets (still in total eclipse) WSW 0°

Observers will also be able to spot Mars, just 7.5° from the Moon; and high in the sky above the Moon will be Fomalhaut, a first magnitude star and the 18th brightest in the sky.
