A penumbral eclipse of the Moon occurred on Friday 18 October, 2013 UT, lasting from 21:50 on 18 Oct–01:49 on 19 Oct UT. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 76% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 3 hours and 59 minutes. The Moon was visible from the Americas (for the end), Europe, Africa, and most of Asia (the beginning of the eclipse will be visible in east Asia).
The timings of the eclipse are as
follows. You would have been able to see the
eclipse if the Moon was up as
seen from your location; but note that this penumbral
eclipse would have been very difficult to see in practice:
| Penumbral eclipse began: |
21:50:41 UT |
| Maximum eclipse: |
23:50:17 UT |
| Penumbral eclipse ended: |
01:49:47 on 19 Oct UT |
During this eclipse the Moon was 8 days after perigee and 6 days before apogee.
At maximum eclipse it was 0.525° in apparent
diameter, which is 1.2% smaller than average.

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 at maximum eclipse,
when it was visible within the bright area on the map. Note that
the map is approximate, and if you
were near the edge of the area of visibility, the moon was very close
to the horizon and may not have been practically visible.
You can use the zoom controls to zoom in and out, and pan to
see areas of interest. 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).
