How to witness rare Blue Moon set to rise in Australian skies in days | #yahooaustraliaAdded:
A rare full moon is set to grace Aussie skies later this week. And if you [music] miss it, you'll have to wait eight years before your next chance. The blue moon, which refers to the second full moon to occur within the same month, will reach a peak on [music] Sunday, May 31st at 6:30 p.m. Australian Eastern Standard Time. But the expected cloud [music] coverage could restrict the moon's visibility for millions of people. Despite the forecast, those in Sydney, Melbourne, Brisbane, and Canberra will have their best chance to see the moon at 6:30. But residents in Adelaide and Darwin will likely get their [music] best view at 6:00 p.m.
Those in Perth, on the other hand, are encouraged to look out for the moon at 4:30 in the afternoon. According to the Royal Museum's Greenwich, a blue moon tends to occur every two to three years, or seven times over 19 years.
