Penumbral Lunar Eclipse (Strawberry Moon)

What Is Penumbral Lunar Eclipse?

When the moon rotates within the outer part of the Earth's shadow, a Penumbral Lunar Eclipse occurs. Such an eclipse is frequently improper for a everyday full moon.


Penumbral Lunar Eclipses in 2020

There could be a lunar eclipse based on the time area on


  • June 5, Strawberry Moon, 
  • July 5 on Buck Moon, and 
  • November 29 on Beaver Moon. 


Why Does Penumbral Lunar Eclipses Happen?


  • The moon shines due to the fact its floor displays the sun's rays.

  • A lunar eclipse occurs while the Earth comes between the Sun and the Moon and blocks some or all of the Sun's light from attaining the Moon.


Imperfect Alignment


  • When the Sun, Earth and Moon are imperfectly aligned, a lunar eclipse takes place.

  • When this happens, the Earth immediately blocks some of the Sun's mild from reaching the Moon's surface and covers all the Moon's exterior with its shadow, also referred to as the penumbra.

  • Since the penumbra is much more fierce than the darkish middle of the Earth's shadow, it is regularly tough to distinguish a ordinary eclipse of the Moon from a full moon.


Two Conditions


For two astronomical lunar eclipses to arise, two astronomical events should occur at the identical time:


  • The Moon need to be in the phase of the Full Moon.

  • The Sun, Earth, and Moon have to be kind of aligned, but not partially carefully aligned for the duration of the eclipse.


Not Every Full Moon Night


  • The cause we do now not see a lunar eclipse every full moon night has to do with the lean of the moon's orbital path. 

  • The plane of the Moon's orbit around the Earth is willing across the Sun at an attitude of five ° to the orbital aircraft of the Earth, which is elliptical.

  • The points at which orbital planes meet are referred to as lunar nodes.

  • Lunar eclipses can only occur whilst a complete moon is near a node.


How to See a Penumbral Lunar Eclipse





  • Unlike a sun eclipse, which can handiest be visible alongside a narrow passage from a small a part of the Earth, the eclipse of the Moon can be seen on all facets of the Earth while an eclipse takes place.

  • One in 3 of all lunar eclipses are penumbral. Even with binoculars, it's far impossible to take a look at the begin and give up of a lunar eclipse.

  • Penumbral eclipses, which consist of the darkest a part of the Earth's penumbral shadow, however, are normally visible to the bare eye. Careful observers can usually look at penumbral eclipses with penumbral magnitudes more than 0.60.
