Don't forget. Occultation of Saturn Thursday April 25, 2019

The Moon facing east at 22:54 am ACST in Adelaide on Thursday 25 April just as Saturn appears from behind the Moon. The Moon is a hand-span from the horizon.

A reminder that there is an occultation of Saturn that can be seen from most of eastern Australia and parts of central Australia, roughly east of a line from Rockhampton to Port Lincoln in the late evening of Thursday 25 April (between around 11 pm ACST and 11:30 pm AEST). The further west you go from the line the lower the Moon will be to the horizon. 

In Woomera the Moon will be just a finger-width above the horiozn, as Saturn exits the dark side of the Moon (at 22:53), in Port Lincoln two finger-widths and in Parachilna (and most of the Flinder's Rangers) the Moon is  three finger-widths anove the horizon as Saturn exits the Moon.
Path of the occultation of Saturn over Australia  (source, IOTA).

You will need a level, clear eastern horizon to see the occulatation at it's best.

Exact timing for several cities and observation hints can be found at my occultation page.

Occultation of Saturn by the Moon 25 April, 2019

The Moon at 22:48 pm ACST in Adelaide on Thursday 25 April just as Saturn appears from behind the Moon. The inset shows the binocular view of Saturn emerging from behind the MoonThe Moon at 23:20 pm AEST in Brisbane on Thursday 25 April just as Saturn appears from behind the Moon. The inset shows the binocular view of Saturn emerging from behind the MoonThe Moon at 23:26 pm AEST in Sydney on Thursday 25 April just as Saturn appears from behind the Moon. The inset shows the binocular view of Saturn emerging from behind the Moon

On the evening of Thursday 25 April Saturn is occulted by the waning Moon as seen from eastern and parts of Central Australia. This is of course the ANZAC day holiday, and many people will be on School Holidays so this is an excellent opportunity to view this normally rare event. Of course  it starts around 11 pm (see table below for exact timings, New Zealand has the best view, see the link below)

The Moon, although low above the eastern horizon, is a very obvious signpost for where to look but for most locations Saturn is behind the Moon as it rises (or the pair are very close to the horizon just before the occultation starts). Adelaide, Townsville and Rockhampton all have the Moon very close to the horizon, so you will need an unobstructed eastern horizon to see the occulation.

Start watching about half an hour beforehand to get set up and familiar with the sky. Saturn will appear from behind the dark limb of the Moon while still low above the horizon, so will be a difficult telescopic target. Reappearance will be hard to see as you have to be looking just at the right moment.

PlaceDisappears Bright Limb Reappears Dark Limb

Brisbane AEST-23:20
Canberra AEST22:3323:26

Rockhampton AEST- 23:15
Townsville AEST- 23:11
Sydney AEST- 23:26


More cities in Australia and New Zealand cities can be found at the IOTA site (UT times only).

Although this can be viewed with the unaided  eye, it is better viewed with binoculars or a telescope. Unfortunately, the occultation is low to the horizon in many places, so large telescopes may not be able to point that low. You sill will be able to enjoy it.

There are two more occulations of Saturn visible from Australia this year, in August  12 (eastern Australia) and September 8/9 (Northern and Western Australia).
