Penumbral Lunar Eclipse:
April 24, 2005
Geographic Region:
eastern Asia, Australia,
Pacific Ocean, Americas
The year's first lunar
eclipse is a deep penumbral
event visible from most of
the Western Hemisphere.
First and last penumbral
occurrences occur at 07:50
UT and 12:00 UT,
respectively. Observers in
eastern North America will
experience moonset before
the eclipse ends, but those
further west will be able to
witness the entire event.
Penumbral eclipses are
difficult to observe.
Nevertheless, a subtle yet
distinct shading should be
visible across the northern
half of the Moon, especially
during the one hour period
centered on maximum.
Greatest eclipse occurs at
09:55 UT with a penumbral
eclipse magnitude of 0.890.
The northern limb actually
passes within 4.4
arc-minutes of the umbra
while the southern limb
remains outside the penumbra
throughout the event.
