A partial lunar eclipse took place on 4 June 2012. It was the first of two lunar eclipses occurring in 2012, the second eclipse set to happen on 28 November. The moon was about 37% covered by the Earth's northern umbral shadow at maximum eclipse.

Visibility[]

This lunar eclipse, occurring during June's "Strawberry" full moon^[1] was completely visible over Australia, rising over eastern Asia and setting over western North America. New England and eastern Canada missed the entire eclipse since the event began after moonset in those regions. The eclipse was visible in the central United States.

Amongst those in North America, observers in western Canada and the USA had the best views with moonset occurring sometime after mid-eclipse.

This simulation shows the earth at the time of greatest eclipse as viewed from the center of the moon. The sun is seen here as a partial solar eclipse over the Earth's north pole.
