March 2007
|
Lunar Occultation of the Saturn (Mar 02, am). There
will be a grazing occultation of Saturn by the Moon on the morning of March
2nd. The moon is leading with its darkest limb forward. Times
from Aberdeen,
Saturn disappears 02:26hUT
Saturn appears 02:45h UT

|
|
|
Total Lunar Eclipse (Mar 03). Approximate
timings :
09:30 pm - partial eclipse starts
10:45 pm - totality starts
11:20 pm - mid eclipse (23:30h UT)
midnight - totality ends
01:10 am - partial eclipse ends
|
|
|
|
Young Crescent Moon (Mar 19, sunset). There
should be an excellent opportunity to attempt a viewing of a very young crescent
moon around sunset on March 19th. Low horizon and clear skies will be needed.

|
|
February 2007
|
Twilight Mercury (~ Feb 07). If twilight
skies are clear in the SW Mercury may be viewed shortly after sunset between
around 3rd and 15th Feb. Best date will be 7th February when the planet
will lie around 18 degrees east of the Sun. Use Venus as a
marker and look between it and and the position where Sun has just set and you
just might glimpse Mercury.
|
|
|
|
Saturn at Opposition (Feb 10). Saturn is
at opposition on February 10, but is well placed for viewing around
midnight throughout the month. Magnitude 0.0 / Size 20" . It is situated
around 8 degrees to the right of Regulus in Leo.
|
|
|
|
Lunar Occultation of the Pleiades (Feb 23). The
Moon (at 1st quarter) will occult the Pleiades open star cluster over the night
of Feb 23-24. The moon is leading with its darkest limb forward and thus
provides the ideal situation for observing the moment of occultation. The
various bright stars of Pleiades will disappear between 22:40 and 23:15pm,
reappearing between 23:30 and 00:10

January 2007
|
Bright comet, C/2006 P1 (McNaught), plunging
towards the Sun (Jan 01 to Jan 15). Comet C/2006 P1 (McNaught)
will approach to only 0.17 AU distance from the Sun at closest approach on
January 13th - this is much closer than Mercury (0.38 AU). Before
then the comet will be visible to the naked eye low in the western sky just
after sunset (to the right of Venus) and in the eastern sky, again very low in
the sky, just before sunrise. Comet is expected to reach +1 to +0
mag in brightness. As the comet approaches the sun it will become more and more
difficult to spot, however it should become easy to see on SOHO's coronagraph
images.

Mercury, Venus and Crescent Moon in early evening sky
(Jan 20). Mercury and Venus will be in SW sky during the latter
part of the month, shortly after sunset. They're joined by a crescent moon on
20th January.

December 2006
|
Moon passes over Pleiades in Taurus during early hours
of 4th December. Conditions will be tricky as the nearly full moon with
outshine the 'Seven Sisters'. However the left hand limb will have a thin
sliver of dark terminator and will be the best location to observe occulations
with binocules or telescope. The 6 brightest Pleiades stars 'disappear' at
times between 02:55 and 04:50h UT (GMT).

Mercury, Mars & Jupiter together in SE morning sky.
Look SE on morning of 10th Dec, at or just before sunrise /
08:15 - 08:45 am and you might catch these 3 planets in close proximity,
just 6 degrees above the horizon.

|
|
Geminid meteor shower is active between 7-15th
December, with peak around 5:00am GMT on 14th December. The Geminid radiant is
just north of the star Caster in constellation of Gemini.

Leonid meteor shower produced by debris from
comet 55P/Tempel-Tuttle. Active between 15-20th November. This year there is a
predicted peak around 04:45hUT on morning of 19th November, with potential rates
up to 100 meteors per hour.

Comet C/2006 M4 (Swan) moving through Hercules
and into Aquila, passing within 3 degrees of Aquila over 28-30 November.

October 2006

Saturn can be found in the dawn sky around 7
degrees WNW of Regulus in Leo. Rings are tilted at around 13 degrees. Look out
for the Moon passing 2 degrees north of Saturn on the morning of 16th October.
|
|
|
|
Orionid meteor shower produced by debris from
Halley's Comet is active throughout the second half of the month, with a radiant
midway between the constellations of Orion and Gemini. Maximum is around 20-22
October (up to 15 meteors per hour).
|
|
|
|
Comet C/2006 M4 (Swan) is expected to reach around
magnitude +8 to +6 by mid October as it passes through constellations of Canes
Venatici, Bootes & Corona Borealis when it then enters into Hercules at
month's end. Should be visible with Binoculars.

A partial lunar eclipse occurs on 7th September. Moon rises partially
eclipsed on the 7th, so look east just before 8pm for this minor astronomical
alignment event. Just the top of the Moon darkened by the Earth's shadow.

Uranus reaches opposition on 5th September.
Lying in Aquarius. the easiest way to find Uranus is with a GOTO
telescope.

August 2006

Neptune will be at opposition on 11th August and
may be worth hunting down if you have a reasonable telescope (setting circles or
a goto mount will help). It lies close to Iota Capricornia. At 8th
magnitude, it will appear star-like through binoculars or as a very small bluish
disk through telescope (at 150x). From Aberdeen it will lie due south
(altitude of 17 degrees) at around 2:10 am BST on 11th/12th August.
|
|
|
|
The Perseid Meteor Shower peaks around 12th-13th
August. A waning gibbous moon may swamp all but the brightest meteors.
|
| . |
|
The last 10 days of August will be best for deep sky objects this month as
the night lengthens and the moon will be out of the way. The Summer
Triangle stars Vega, Denab and Altair are more or less due south in late
evening. Look out for the bright summer Milky Way
which can be streaming from Cygnus high overhead, down through Aquila and Scutum.

Comet 4P/Faye passes through Pisces during
August and will pass close to M74 around August 29 (ESE sky, 34 degrees
Altitude, midnight BST). Likely to be +13 magnitude at beginning of month
but expected to bright to +11.5 to +12 by end of August (a telescope will be
needed).

July 2006

Jupiter appears to stand still in Libra on the
6th of the month, and moves very little during July. Sitting above the southern
horizon as it gets dark, the planet is still very bright. As the night wears on
it moves to the south-west, setting around 1.30am at the start of the month, but
well before midnight by the end. May be worth taking a look with a
telescope and try to spot the Great Red Spot and
the currently adjacent Red Spot Jr. Sky
