Best seen: moonrise on Sunday, August 18 and Monday, August 19 The third full moon of winter in the southern hemisphere, the “Sturgeon Moon”—also known as the “Lynx Moon” and the “Lightning Moon”—will be what astronomers call a seasonal blue moon. That’s because it will be the third of four full moons in one astronomical season, which occurs only rarely. It will also be the first of four “supermoon” full moons in 2024, albeit the smallest. The night after it turns full, the moon will shine close to Saturn. As a bonus, from North America the full moon will rise close to sunset on two successive evenings—so you get two chances to see this very special sight. The name of this moon comes from the sturgeon fish abundant in the Great Lakes and other North American lakes during August.
