AS THE MOON MAKES its way
eastward along the ecliptic this
month, it eclipses two planets and
a moderately bright star. The first of
these events occurs on the night of
October 11-12, when the 94%-illuminated,
waning gibbous Moon
makes Uranus vanish temporarily
for observers across the western half
of the U.S. (including Alaska) and
much of Canada. The planet's disappearance
at the bright lunar limb
occurs before midnight (daylightsaving
time) on the 11th for the
Mountain and Pacific time zones,
and shortly after midnight for the
Midwest and Great Plains.

5.7 with a disk 3.8″ across that'll
require a modest-size telescope to
pull from the lunar glare. Its reappearance
along the dark lunar limb
will be easier to observe. The Moon's
angle of approach varies depending
on your location. The more
oblique its path, the more gradually
it'll cover the planet. For example,
in Minneapolis, Minnesota, where
the southern limb nicks Uranus,
the Moon takes about 22 seconds
to completely eclipse it. In Seattle,
Washington, where the occultation
is more central, the Moon covers
the planet in about 8 seconds. Some
places will see the lunar limb graze
Uranus. For a list of disappearance
and reappearance times visit https://

Next, in the predawn hours of
Looking East
October 20th, the 24% waning
crescent hides 3.5-magnitude Eta (η)
Leonis in Leo's Sickle. Once again,
the western half of the U.S., along
with southern Canada and northern
Mexico, are favored. Observers
as far east as Ohio might be able to
spot the star perched on the Moon's
western limb around sunrise.
There's evidence to suggest Eta
may have a close companion star, so
