A partial eclipse of the Moon occurs on Monday 27 July, 2037 UT, lasting from 01:18–06:58 UT. The Moon will be strikingly shadowed in this deep partial eclipse lasting 3 hours and 12 minutes, with 81% of the Moon in darkness at maximum. The eclipse will be visible in the Americas and western Europe and Africa.
The timings of the phases of the eclipse are as
follows. You will be able to see each phase of the
eclipse if the Moon is up at the corresponding time as
seen from your location; however the penumbral phase
will be very difficult to see in practice, so you may want to start watching at the partial phase:
| Penumbral eclipse begins: |
01:18:07 UT |
| Partial eclipse begins: |
02:32:16 UT |
| Maximum eclipse: |
04:08:30 UT |
| Partial eclipse ends: |
05:44:41 UT |
| Penumbral eclipse ends: |
06:58:56 UT |
During this eclipse the Moon will be just 4 days before apogee, making it fairly small.
At maximum eclipse it will be 0.508° in apparent
diameter, which is 4.3% smaller than average.
The statistics page has information on the ranges of the sizes of
the Sun and Moon, and the Moon data page displays detailed
information on the Moon's key dates.
Interactive Map
This map shows the visibility of the eclipse. The bright area in the
middle will see the whole eclipse; the yellow band to the right will see
the start of the eclipse, and the blue band to the left will see the
end. Note that the map is approximate,
and if you are near the edge of the area of visibility, the moon will be
very close to the horizon and may not be practically visible.
You can use the zoom controls to zoom in and out, and pan to
see areas of interest. Hover your mouse over the
tags to see what will be visible from each area on the map. The green
marker in the centre shows where the Moon will be directly
overhead at maximum eclipse.
The interactive map is currently not available.

Note that while all dates and times on this site (except
where noted) are in UT, which is within a second of civil time,
the dates and times shown in NASA's eclipse listingsGSFC Eclipse Web Site
The primary source of all the information on eclipses presented here at Hermit Eclipse. (NASA Goddard Space flight Center)
are in the TDT timescale.
The Sun and Moon distances are shown in km, and as a
percentage of their minimum - maximum distances; hence 0%
is the closest possible (Earth's perihelion, or the
Moon's closest possible perigee) and 100% is
the farthest (aphelion, the farthest apogee).
