First got here a photo voltaic eclipse. Then a “strawberry moon.” Now, celestial fanatics can sit up for seeing an excellent blue moon this week beginning Monday.
The total moon, which will probably be each a supermoon and a blue moon, will grace the skies Monday and can seem full till early Wednesday morning, in line with NASA. It’s thought of each a supermoon and a blue moon due to its proximity to earth and its timing through the season.

“It’s rising farther south than the winter solstice solar,” Vanessa Alarcon, the astronomical observer on the Griffith Observatory, instructed The Instances final week. “It’s really fairly spectacular if you see it.”
Griffith Observatory has moonset strains on its decrease West Terrace, pointing to the precise spots on the horizon the place the most important lunar standstill will happen. However it must be viewable to anybody when it rises above the jap horizon and sinks on the western horizon, Alarcon stated. The phenomenon will happen by way of a lot of 2025.
