On Tuesday 10 June, Antares, the brightest start in Scorpio, is occulted by the Moon as seen from the all of Australia and New Zealand. (see the table below for major cities and see the IOTA site link below for more locations). In Western Australia the occultation starts in the twilight,
The occultation occurs with the moon well above the eastern horizon when the sky is fully dark for the Eastern and central states. Perth and Western Australia generally sees the occultation start low above the horizon during twilight.
Disappearance and appearance times are given in the table below. Other locations will see the occultation at a similar time for cities at a similar latitude (eg Woomera is similar to Adelaide).
While the occultation is visible to the unaided eye (although the Moon being nearly full will make it difficult), the sight will be better in binoculars or a small telescope. Set up ahead of time so that you can be sure everything is working well and you can watch the entire event comfortably. Antares will be clearly visible to the unaided eye near the Moon. Other sites can be found at IOTA (timings in UT)
