Mercury is at its greatest Eastern elongation for this apparition, (See This Table), at an angle of 24° on the 9th and finishes off the evening apparition it started last month. See May’s Page for details. On the 4th the Moon passes 3.5° South of Mercury in the early hours of the morning.


Venus, at superior conjunction on the 11th, lies directly behind the Sun as seen from the Earth.


Mars is not on view this month.

MARSWATCH – latest observations of the red planet.


  • Vesta 0.04° North of Moon on 19th and stationary on 4th.
  • Juno stationary on 23rd

Jupiter is now a morning object in the constellation of Taurus but will rise only one hour before the Sun does. From the 24th follow the Moon as it becomes a thin crescent and heads towards the Sun On the morning of 29th, Jupiter will be 5° above the Moon.

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 can be close to Jupiter in the morning sky, with Jupiter the brightest of the two. Look at the close groupings of Moon, Jupiter and Saturn around the 28th of the month.


Both planets rise before midnight by the end of the month so those patient enough to wait up until the early hours will be amongst the first to get a glimpse of these two planets. Even if you cannot see them directly a few long exposure photographs of the region using a 135mm lens will reveal them when the photo is compared with a good star atlas which shows faint stars.

Pluto can be found in Ophiuchus, roughly between the 4th magnitude stars zeta and 20 Ophiuchi. The best time to look for the planet is around New Moon. The dates below will be a guide for planning observations.

Positions for June are when pluto's elongation angle is greater than 90°.
