Residents of Jackson, Wyoming, have a celestial treat in store as a blue micromoon is set to grace the night sky this weekend. This unique event occurs when the second full moon of the month reaches its peak fullness, which is expected at 2:45 a.m. on Sunday, May 31.

Understanding the Blue Micromoon

The term ‘blue moon’ refers to the occurrence of a second full moon within a single calendar month. Meanwhile, the ‘micro’ aspect of this event is due to the moon being at its apogee, the farthest point in its orbit from Earth, making it appear smaller and dimmer than usual. According to NASA, the moon will be approximately 251,000 miles away from Earth during this time.

In contrast, a supermoon occurs when the moon is at its perigee, the closest point to Earth in its orbit, roughly 226,000 miles away. The next supermoon is anticipated in November, offering a brighter and larger view of the moon.

Weather Conditions May Affect Viewing

While the blue micromoon presents a rare opportunity for skywatchers, weather conditions may pose a challenge. Buckrail Meteorologist Alan Smith has forecasted high chances of rain on Saturday, which could obstruct the view of the nearly full moon. Residents are encouraged to catch a glimpse of the moon before the weather turns.

The first full moon of May peaked on May 1, making this upcoming event the second and final full moon of the month. Whether you’re an avid astronomer or simply enjoy the beauty of the night sky, this weekend’s blue micromoon is a spectacle not to be missed, weather permitting.
