Click on the monthly image to get a larger high resolution view of the night sky set for 53° N (Horncastle, England) but is usable for the UK and Eire. All charts are set for the 1st of the month at 22:00 GMT (10pm) and can be used on the other dates and times shown in each corner of the chart.
Solar System quick summary
For most charts see the buttons at the top for various planets etc.. Charts & images in the text can be clicked to give a larger view.
Venus is in conjunction with M44 in the morning sky on the 1st and lies next to Regulus on the 20th. Jupiter lingers in the evening twilight sky and is in conjunction with Spica on the 5th. Saturn also lies in the evening sky but still viewable all month. Neptune comes to opposition on the 5th and is now viewable all night. Uranus is also rising earlier and becoming well placed to view. Pallas moves south through Eridanus slowly brightening. Ceres lies in the morning sky moving from Gemini into Cancer. Mercury has its best morning apparition and lies close to Mars on the 16th & 17th as Mars climbs out of the morning twilight. The Moon occults Gamma Librae on the 24th. Vesta lies too close to the Sun to be viewed.
If you have a telescope then why not take a look? The chart here gives you some of the features to look out for.
Now it is time for the furthest official planet in our solar system as Neptune now comes to opposition on September 5th and so becomes viewable all night. It has been lucky for us that pretty much all year it spends its time not far from mag 3.7 Lambda Aquarii helping to locate it. It is such a slow mover due to its distance from the sun that the author photographed them on July 31st 2016 as shown in the image below right taken with an Equinox 80ED refractor and Canon 50D DSLR. Neptune will be viewable in a 10x50 binocular shining at mag 7.8 so considerably fainter than Lambda. Neptune is retrograding and next month passes below Lambda as shown on our chart below. Interestingly the almost Full Moon lies to the right of Neptune and Lambda on the 5th and it reaches 'Full' phase at 08:03 BST next morning but all of them will have set by then.
Now for a busy morning sky! Venus has a gorgeous close encounter with the Beehive cluster, M44 on the morning of the 1st when it lies under the cluster as they rise. The view at far left shows a wide field, nearly naked eye, view so the really bright 'star' will be Venus. Look with a binocular and you get the RHS chart view and the inset shows the phase of Venus as seen through a telescope at high magnification. Both charts are set for 05:00 BST. The binocular view shows Venus daily as it moves past the cluster.
Then on the 18th as Venus approaches Regulus in Leo, the slim crescent moon joins them for a lovely sight, the wide field shows them on that date. Two mornings later and Venus lies close to Regulus on the 20th as a finale. Both events are shown here and the time is set for 05:30 BST looking East and there is a bonus -
So the mornings belong to Venus -
On that morning Mars is also north of Regulus so the first of the sequence of views below shows a snapshot of them with Mercury to their right. Note the scale -
For a difficult finale on the 19th a, just over 24 hour old, slim crescent moon lies below Mars and Mercury as shown here at right, look around an hour before sunrise to try to spot them! As Mercury drops back into the solar glare at the end of the month so Mars climbs higher but watch as Venus is now heading for a close encounter with the Red planet early next month to continue the early morning twilight fun.
Also look out for the following:
Sept 1st Moon lies close to Teaspoon asterism (evening)
Sept 5th Jupiter again in conjunction with Spica (evening twilight)
Sept 7th Ceres lies south of Kappa Geminorum / Pallas lies close to Zeta Eridani -
Sept 11th Moon forms triangle with M45 and Aldebaran as they rise tonight
Sept 21st Slim Crescent Moon to right of Jupiter in bright evening twilight
Sept 22nd Crescent Moon lies to the left of Jupiter (evening)
Sept 24th Moon occults Gamma Librae (disappearance only)
Sept 25th Crescent Moon lies north of Antares in the evening
Sept 26th Moon lies near to Saturn this evening
Sept 28th First Quarter Moon lies close to Teaspoon asterism (evening)
Clear skies and happy sky watching.
