A partial eclipse of the Moon shall be seen from throughout the UK on the night of 16/17 July, with the Moon rising already partially immersed in Earth’s deep umbral shadow.

The Moon rises at round 9pm BST (20:00 UT ) and because it climbs slowly away from the murky south-eastern horizon it shouldn’t be too troublesome to identify an rising fraction of its disc changing into darkened behind the curved shadow of the Earth. How clearly outlined the lunar options coated by Earth’s shadow and the sting of the shadow itself seem throughout the eclipse will depend on native sky circumstances. Be sure to have a pair of binoculars with you.

For this eclipse, 65.three per cent of the Moon’s diameter shall be coated in deep shadow on the time of best eclipse. This happens at 10.30pm BST (from London), by which era the Moon has hauled itself about eight levels away from the horizon. The tip of the umbral part of the eclipse happens at midnight (BST), with the Moon at an altitude of round 15 levels.

The ultimate chapter of this eclipse options the very delicate penumbral part, when our satellite tv for pc has moved wholly out of Earth’s deep umbral shadow. The penumbral phases of an eclipse are by no means straightforward to see, and with the Moon hanging comparatively low over the south-eastern horizon, you’ll want pristine native sky circumstances to see the ill-defined fringe of Earth’s outer shadow steadily retreating throughout the lunar disc. The tip of the penumbral part at 1.17am BST indicators the top of the eclipse.
