A penumbral lunar eclipse is visible on the night of 5-6 May 2023 for observers positioned in Asia, Australia, New Zealand, the Middle East and Antarctica.<\/p>\n

It will also be visible in parts of mainland Europe during moonrise.<\/p>\n

What observers will see is a subtle darkening of the Moon during the event but, it has to be said, not the spectacular reddening that occurs during a total lunar eclipse<\/a>.<\/p>\n

The eclipse begins at 15:14 UTC on 5 May, 2023, but the Moon will not be visible at this time for those in the UK or North and South America.<\/p>\n

Greatest penumbral eclipse will occur at 17:22 UTC on 5 May and the event will end at 19:31 UTC, so be sure to convert the timings for your own timezone.<\/p>\n

In all, the event will last for 4 hours 17 minutes.<\/p>\n

What is a penumbral lunar eclipse?<\/strong><\/h2>\n

When a shadow is cast by any object from an extended light source, we observe two things: a dark inner umbral shadow and a lighter outer penumbral shadow.<\/p>\n

Consider that extended light source is the Sun, and the shadow in question is cast by Earth on the Moon.<\/p>\n

This produces a dark umbra and a weaker, more subtle penumbra.<\/p>\n

Whereas umbral lunar eclipses are quite impressive, penumbral lunar eclipses are much more subtle, and you may need to concentrate quite hard to appreciate the change in appearance.<\/p>\n

It also helps, of course, to get your timings right, as then you\u2019ll know exactly when to look.<\/p>\n

The penumbral shadow creates a weak gradient across the Moon\u2019s disc, and you may get the best results by photographing the penumbral lunar eclipse with a DSLR camera.<\/p>\n

The Moon is a bright object, which makes it suited for DSLR imaging. A low ISO is recommended. Find out more in our guide on how to photograph the Moon<\/a>.<\/p>\n

Try taking one image before or after the eclipse and one at the point of greatest immersion, then comparing the two.<\/p>\n

A lens on a tripod will work, but of course equatorial tracking will keep the Moon in frame and make the process much easier!<\/p>\n
