Other names
It is also known as the Crow Moon, the Sap Moon, the Lenten Moon. Most popular moon names today come from the North American Farmer's Almanac, which collected names from Native American, colonial and European sources. Old English and Celtic month names are a different tradition, and few authentic British moon names survive.
Ways to mark it
- Step outside at moonrise and watch it clear the horizon, when it looks largest.
- Write down what has grown since the last new moon, and what you are ready to let go of.
- Set crystals on a windowsill overnight, the traditional way to cleanse them (bring in soft or water-sensitive stones if it is damp).
- Light a white or silver candle and sit quietly for ten minutes.
Photographing the full moon
Shoot at moonrise, when there is still some light in the sky and the moon sits near buildings or trees for scale. On a phone, tap the moon and drag the exposure down until surface detail shows.
