何为蓝月亮？如何观赏2026年最小满月
On the night of June 1, 2026, stargazers across China were treated to a captivating lunar display as the smallest full moon of the year rose in the east. This full moon was also a 'Blue Moon,' a term that added an extra layer of intrigue for those who ventured outdoors to observe it. Despite its name, the moon did not appear blue; instead, it shone with a gentle, silvery glow, visibly smaller and dimmer than a typical full moon.
A Blue Moon is a celestial occurrence that has two widely accepted definitions. The most common definition, popularized by a misinterpretation in the 1940s, refers to the second full moon within a single calendar month. The older, seasonal definition describes it as the third full moon in an astronomical season that contains four full moons instead of the usual three. Either way, a Blue Moon is a relatively rare event, happening roughly every two to three years, hence the phrase 'once in a blue moon.' The June 1 full moon fell under one of these categories, making it a notable event for sky enthusiasts.
