Mercury |
Round about the middle of the month, Mercury appears above the eastern Horizon at civil twilight - 40 minutes or so before sunrise. The unmistakable shape of Leo lies above Mercury when it is at its highest altitude above the horizon - which is at its brightest towards the end of the month as it starts to dip towards the Sun.

Venus |
Venus is too close to solar conjunction to be a favourable object.

Mars |
|
Mars’ elongation for the Sun is only 38° mid-month and as it is relatively faint it will be a hard object to fins in the evening sky, setting only an hour after the Sun by the 30th.

Jupiter |
|
Jupiter is at opposition on the 21st and is therefore at its best for observation. Presenting a nice, big disk almost 50” across even a medium magnification will reveal detail about the planet’s cloud tops and binoculars show its four Galilean satellites clearly. Is your eyesight so good that you can see any of the satellites with your naked eye?
They are certainly bright enough but without optical aid, they are very close to the planet.
On the 18th there is a very favourable conjunction between Jupiter and Uranus with the latter lying less than a degree to the north of Jupiter.
On the 23rd at 0700 Jupiter is 6° south of the Moon.

Saturn is poorly placed in the constellation of Virgo. After its solar conjunction last month it will be a little while before it’s available for viewing again.

Uranus |
More info... |
Uranus is at opposition on the 22nd in Pisces. As it is quite low down as seen from the UK, it is not usually an object to search for under light-polluted skies but as mentioned above it is currently ideally placed, lying less than a degree north of Jupiter. It is bright enough to be visible using binoculars but a high magnification is necessary to reveal the ‘star’ as a small planetary disk.

-
The Piscids have a double maximum this month; on the 9th and 21st. The 9th is favourable, but the 21st, is not due to a full Moon on the 23rd. rate are around 5 per hour can be expected on both dates.
-
The Alpha Aurigids reach their second maximum of the year on the 15th and is fairly favourable this year.
