Saturday April 7, Occultation of Antares.

There is an Occultation of Antares by the Moon on Saturday April 7. This is visible in New Zealand, Central and Eastern Australia. In Eastern Australia, Antares passes behind the bright limb of the Moon shorthly after Moonrise, in Central Australia the Moon rises after Antares has gone behind it. In New Zealand, the Moon is a decent height above the horizon before Antares disappears. Antares emerges from behind the Moon at (local times) 21:10 Adelaide, 21:26 Brisbane, 21:39 Canberra, 21:43 Melbourne, 21:36 Sydney and 23:41 Auckland. Full occultation start and stop times are at Southern Skywatch now.

Antares is bright enough so it can be readily seen with the unaided eye against the Moon, although binoculars or a telescope will give a better view. Seeing Antares "pop out" from behind the dark side of the Moon is pretty groovy, so why not have a look?
