NIGHT SKIES
Events during August
Solar eclipse - 1st August.
Lunar eclipse - 16th August
The Moon: New – 1st and 30th, Full – 16th.
The Perseids metor shower is visible from 23rd July until 20th August, at maximum on the 12th August. Visibility in 2008 is unfavourable due to the Moon becoming full on the 16th, the light from which interferes with the number of meteors that can be seen. An average hourly rate of 60 is expected.
Mercury
Astronomy, Mythology & Astrology of Mercury
Mercury is moving eastwards away from the Sun and southwards in declination, making observation difficult from northern latitudes. It is better placed to be seen as latitudes decrease.

The best times to observe Mercury are when it is an evening star in the spring and a morning star in the autumn. In midsummer the lighter skies make visibility difficult near the horizon.

Venus
Astronomy, Mythology & Astrology of Venus
Venus remains at -3.9 magnitude moving slowly out from the Sun. It is visible low in the western horizon after sunset. Venus is in the same region of the sky as Mercury, passing within 1 on 21st August.

Transit On the 8th June 2004, Venus was at inferior conjunction and transited the sun. Transits of Venus are rare, taking place at greater than 100 year intervals and usually in pairs. The last two transits of Venus were in 1874 and 1882. June's transit began at 7.20h and lasted 6 hours until 13.20h, the total event visible from Europe as a small black disc crossing the lower part of the Sun from left to right. The next transit will be in late June 2012. After that, transits of Venus won't occur again until 2117 and 2125.

Before and after inferior conjuction, when Venus is the closest it comes to the Earth, are the times at which the planet is most brilliant and can be seen setting or rising 4 hours after or before the Sun. The dates of the next two inferior conjunctions are October 28th 2010 and October 26th 2018.
Mars
Astronomy, Mythology & Astrology of Mars
Mars remains an evening object at +1.7 magnitude, moving from Leo into Virgo during August. In low northern latitudes and further south it can be seen low in the western evening sky.

At opposition on the 28th August 2003, Mars was only 56 million kilometres from the Earth. It showed a disc of 25.1 seconds of arc across which is almost as large as it can ever appear. Mars started 2003 at 310 million kilometres from the earth at 4.5 seconds of arc and 1.6 magnitude. By opposition it brightened 50 times to reach -2.9 magnitude but faded to 0 magnitude by December. Even to the naked eye Mars was a striking object in the summer and autumn sky, easily identifiable by its reddish hue in an area of sky poor in bright stars. Mars will not be as close again until 2018.

These favourable oppositions occur every 15 or 17 years but other oppositions occur at average intervals of 2 years 2 months during which time the planet makes a complete circle of the Earth. In general Mars is observable every other year, being too close to the sun for favourable conditions during other times. Brightness at opposition varies from -1.0 to -2.9 magnitude, and when furthest from the earth it fades to 1.7 magnitude. The planet can be identified by its orange-red colour.

As in 2003, Mars comes nearest to the Earth at oppositions at the end of August. At these times it can be brighter than Jupiter, although low in the sky in Aquarius for northern observors. In the northern hemisphere, the planet may be better seen at oppostions during autumn and winter months when it is higher in the sky.

Jupiter
Astronomy, Mythology & Astrology of Jupiter
Jupiter remains a brilliant object at -2.6 magnitude. During August the planet is visible throughout most of the night, from sunset to early morning twilight.

Being 770 million kilometres from the sun, the difference in brightness between opposition and conjunction varies less than with Mars, from about -2.8 to -1.8 magnitude. Always a bright planet, Jupiter comes to opposition a month later each year, moving approximately from one zodiacal constellation to the next.

The 4 largest moons of Jupiter are easily visible through a small telescope, ranging from 4.6 to 5.6 in magnitude. The innermost, Io, takes 1.8 days to orbit the planet making its motion easily detectable within a few minutes.

Saturn
Astronomy, Mythology & Astrology of Saturn
Saturn, at magnitude +0.9, is low in the western sky but, due to the long summer twilight, is difficult to observe in high northern latitudes. Further south it can be seen for a short while during early evening until the middle of the month.

Saturn moves more slowly than Jupiter and can remain in the same constellation for several years. The brightness of the planet depends on the aspect of its rings, as well as its distance from Earth and the Sun.

The planet crossed the equator into the northern hemisphere in 1996 where it will remain until 2010 with the southern side of the ring system facing the earth. Because of its distance, its brightness varies little between opposition and conjunction but is affected by the huge ring system. Seen edge on the rings contribute little or no light.

Every 15 years the plane of Saturn's rings passes through the sun, illuminating first the north and then the south side. For a few days the rings are edge on to the sun. About the same time the Earth passes through the ring plane and, depending on the Earth's position, this may happen just once or 3 times. During 1995/96 there was a triple crossing and the next will be 2038/39. The next single crossings will be in 2009 and 2025.

Saturn's largest moon, Titan, is visible in small telescopes orbiting outside of the ring system.

Uranus
Astronomy, Mythology & Astrology of Uranus
Brightness varies slightly reaching 5.6 magnitude at opposition. This is bright enough to see with the naked eye but identifying it against the stars is difficult.
Neptune
Astronomy, Mythology & Astrology of Neptune
Neptune reaches opposition on the 15th August in the constellation of Capricorn. At +7.8 magnitude, it is not visible to the naked eye. At opposition Neptune is 4,342 million kilometres (2,698 million miles) from Earth.

Neptune has an average magnitude of 7.9 which varies little with changing distance.

Pluto
Astronomy, Mythology & Astrology of Pluto
No longer an offical planet and never brighter than +13 magnitude, Pluto is only visible through powerful telescopes.
