Lunar Eclipse 2018
A total eclipse of the Moon will occur on July 27. Weather permitting, this will be the most central lunar eclipse since June 15 2011.
This eclipse will be visible from India, Africa and Europe but not from north America.
However, only the latter part of the eclipse will be visible from the UK as the Moon will rise above the horizon in full eclipse.
This is a fairly central eclipse insofar as it will have a gamma value of 0.11 (where a value nearest 0 is most central, and that values can range between -1 and +1 is the limit of the earths umbral shadow) – typically more central eclipses are a deeper red hue at greatest eclipse.
Here are the Gamma (G) values for previous lunar eclipses:
- 2011-06-15 G:0.0899
- 2011-12-10 G:-0.3883
- 2014-04-15 G:-0.3017
- 2014-10-08 G:0.3827
- 2015-04-15 G:0.4460
- 2015-09-28 G:-0.3296
- 2018-01-31 G:-0.3014
- 2018-07-27 G:0.1168
The all important times for the various stages of the eclipse are provided below (in UT)
- Enter Penumbral shadow (P1) – 17:14
- Enter Umbral shadow (U1) – 18:24
- Fully within Umbral shadow (U2) -19:30
- Greatest or Mid eclipse – 20:21
- Exiting Umbral shadow (U3) – 21:13
- Fully exited Umbral shadow (U4) – 22:19
- Exited Penumbral shadow (P4) – 23:38
Totality (within part of the Umbral shadow) will last for 3h 54m (1h 43m within complete shadow)
Umbral Magnitude is expected to be 1.6

- Leeds – 20:10
- Cardiff – 20:06

Viewing the Eclipse
The majority of the 2nd half of the eclipse shall be visible from all of the UK. However, if you are further north than Carlisle and the Kiedler Forest the moonrise will occur after mid eclipse. The further south and east you are, the more you’ll be able to view.
However, you’ll have to travel to the Continent to view the start of the eclipse as this isn’t visible from anywhere in the UK.
That being said, I’m sure that we shall see a slew of amazing photos – a deep red eclipsed full moon coming over the horizon will surely be quite a sight.
