The largest supermoon of 2022 — July's full Buck Moon — rises above the eastern horizon tonight. 

It will make for a striking skywatching sight as "supermoons shine about 16% brighter and appear 6% larger than an average full moon" writes geophysicist Chris Vaughan, an amateur astronomer with SkySafari Software who oversees Space.com's Night Sky calendar

The Buck Moon, also called the Thunder Moon, or Hay Moon, will reach its full phase at 2:38 p.m. EDT or 11:38 a.m. PDT (18:38 GMT), according to Vaughan. It will shine brightly between the constellations of Sagitarrius and Capricornis.

The exact time of the event varies depending on your specific location, so you'll want to check out a skywatching app like SkySafari or software like Starry Night to check for times. Our picks for the best stargazing apps may help you with your planning.

A full moon occurs when the moon and sun are opposite each other and sunlight strikes the moon face-on. As such, it can be tricky to see features on the lunar surface in detail during a full moon due to the lack of shadows.

Supermoons occur when the full moon coincides with the moon's closest approach to Earth in its orbit — known as perigee. According to the Farmer's Almanac (opens in new tab) and Fred Espanak (opens in new tab), eclipse expert and retired NASA astrophysicist, there are four supermoons in 2022, in May, June, July and August. Espanak's definition of a supermoon as a full moon within 90% of its closest approach to Earth gives us four to view this year. 

July's full moon is not just an impressive skywatching target but is also an important event in many different cultures worldwide. Here are some examples of the cultural significance of July's full moon according to NASA (opens in new tab)

  • Europeans sometimes call this the Hay Moon due to the haymaking season that falls between June and July. 
  • Hindus, Buddhists, and Jains may call July's moon the Guru Full Moon (Guru Purnima), "celebrated as a time for clearing the mind and honoring the guru or spiritual master," NASA said.  
  • Theravada Buddhists may call July's moon the Asalha Puha (also known as Dharma Day or Esala Poya — a festival celebrating Buddha's first sermon, NASA said). July's moon also marks the beginning of a three-month annual Buddhist retreat called Vassa.  
  • July's full moon falls in the middle of the sixth month of the Chinese calendar, Tammuz in the Hebrew calendar and Dhu al-Hijjah — the 12th and final month of the Islamic calendar.
