|PHASES OF THE MOON DURING OCTOBER 1999|
THE PLANETS THIS MONTH.
Although Mercury reaches its greatest Eastern elongation on the 24th, which means that it should be visible as an eveing object, the angle of its orbit with respect to our Northern horizon is shallow which means that it doesn’t appear above the horizon at all at the time of civil twilight.
In the middle of the month Venus is at its highest point above the horizon. Its’ greatest elongation is on the 30th when it lies 46°.5 West of the Sun in the morning sky. Phase is 43% diameter 28″.
Mars still features in the evening sky, but is now at its furthest south of the apparition in the constellation of Sagittarius. It has shrunk below 7′ in diameter and it is now difficult to see the surface markings. CCD observers with a good Southern aspect may still be able to get reasonable images. On the 16th the Moon passes 4.5° South of Mars.
MARSWATCH – latest observations of the red planet.
- 85 IO and Undina are at oppostion this month at Mag 10.
- 16 Pysche and 198 Ampella remain on view from last month.
- 216 Kleopatra, 354 Eleonora, and532 Herculina are all well placed at 11th Mag.

Jupiter reaches opposition on the 23rd and is a huge 49″ across, and makes a fine sight in telescopes. On the 24th the Moon passes a wide 4.°5 South of the planet.
Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.
Saturn is nicely placed, lying a little way to the left of Jupiter. Jupiter will start to overtake Saturn in the middle of 2000, the first time the two planets will be in the same small region of the sky at the same time since 1981.
URANUS and NEPTUNE.
Both are still with us, but by months end are hiding in the South Western horizon’s murk, within the constellation of Capricornus . Uranus should be visible through binoculars under a clear, dark sky, but Neptune may need further resolving power – i.e. a telescope – to distinguish it from a star.
Planet Positions During October 1999:
Uranus Oct 1st R.A. 21h:02m:57s DEC -17°:33':50" Mag 5.7 Neptune Oct 1st R.A. 20h:15m:16s DEC -19°:32':19" Mag 7.9
Tiny distant pluto is now very poorly placed for observations from Liverpool. Please note even at opposition Pluto reachers 13.7 Mag.
