IF YOU LOOK up at the stars tonight, you may be able to spot a lunar eclipse.

Should you be lucky enough to get a break in the clouds between 9.24pm and 10.04pm tonight, there will be a penumbral eclipse of June's full moon - also known as a 'Strawberry Moon Penumbral Lunar Eclipse'.

The Argus' Night Sky columnist Jon Powell, from Ebbw Vale, explained the difference between tonight's eclipse and a full lunar eclipse or partial eclipse.

"June's full moon is referred to as a Strawberry Moon, as the berries mature and ripen ready for picking at this time of year," he said.

"A penumbral eclipse of the Moon is when the more diffused outer shadow of Earth, the penumbra, falls on the moon’s face.

"This third kind of lunar eclipse is much more subtle, and much more difficult to observe."

Mr Powell offered some advice for observing the eclipse.

"June's full moon will rise at 9.24pm so the lunar surface will already be in a state of penumbral eclipse," he said.

"With the eclipse ending at 10.04pm there is only a very short window of opportunity to view the spectacle.

"Given the bright twilight in the evening sky, plus the fact that the eclipse itself is fairly dim, and it will take the most eagle-eyed among us to view the partial dimming."
