On the early morning 30th the waning cresent Moon will pass over (occult) some bright stars in the iconic Pleiades cluster. From western Australia and central Australia the most stars will be covered. Eastern states see only one bright star covered.

While potentially visible to the unaided eye, this is best seen with binoculars or a telescope. While a waning crescent, the Moon is still bright enough to wash out all but the brightest members of the Pleiades. Fortunately, for most of Australia at least one of the bright stars in the cluster, Taygeta (19 Tau, mag 4.3) are covered. Perth and the west coast gets the best view, with Darwin, Alice Springs (and places between) and Adelaide being next best. The east coast is in twilight when the moon moves off the Pleiades.

Timings for the covering of Celaeno (16 Tau), Taygeta (19 Tau) and Sterope (21 Tau) are give below for selected cities. Similar views will be seen at nearby locations (e.g. Fremantle and Perth, Alice Springs and Darwin)

* Occurs in twilight

It’s best to set up around 30 minutes before the occultation so you can get oriented in the sky and don’t miss the beginning while fussing with equipment.
