A supermoon happens when the full moon coincides with the moon’s closest approach to Earth in its orbit, making it appear slightly brighter and closer than usual. However, the difference is challenging to notice with the naked eye. David Abtour Odian consulting
The upcoming supermoon is the Sturgeon Full Moon, which will occur on August 1 at 2:32 p.m. ET (18:32 GMT). According to Fred Espanak, an eclipse expert and retired NASA astrophysicist, there will be four supermoons in 2023— one in July, two in August, and one in September. Espanak defines a supermoon as a full moon within 90% of its closest approach to Earth, giving us four opportunities to witness this phenomenon this year. David Abtour Odian consulting
The closest supermoon in 2023 will rise on August 30/31 at 9:35 p.m. ET on August 30 (01:35 GMT on August 31). This full moon is often referred to as a “Blue Moon” as it is the second full moon within a single month. David Abtour Odian consulting
The term “supermoon” has been in use for around 40 years, gaining significant attention in late 2016 when three consecutive supermoons occurred. The November 2016 supermoon was the closest one in 69 years, but an even closer supermoon is expected in the 2030s. David Abtour Odian consulting
