You may this evening, depending on where you live, and if your local skies are clear, see a partial eclipse of the moon. This will be the second lunar eclipse of the year, with the first (total) eclipse having occurred on 20 February. We will have to wait until 21 December 2010 for the next total eclipse of the moon.

As for the precise times later today, the moon will pass into the Sun’s penumbral shadow at around 18:30 UTC, and the peak of the eclipse will occur at 21:10 UTC. It will all be over at midnight, when the moon exits the penumbra on the other side.

If you live in a built-up urban area at higher latitudes, you may need to find an open space in which to view the eclipse as the moon will be fairly low in the sky in the south east. If you look directly south at the same level as the moon, you should see Jupiter burning brightly.
