The Doncaster night sky this month

The September Night Sky

These are the areas of sky you should be able to see looking in the direction of sky mentioned at around the 15th of this month, about 10:30pm BST.

Remember, stars (and planets can be included) appear to rise and set 4 minutes earlier on each successive day. This equates to 1 hour every 15 days. Therefore on the 30th, the maps will show the sky for 9:30pm BST. While, on the 1st of the month, the maps will show the sky for 11:30pm BST.

Notes: Unofficially known as the start of the new sky observing season. The nights are noticeably starting to get earlier and darker. By 9pm BST the sky is dark enough for the bright stars to be seen.

By the 1st, Mars is already in the sky but a paltry 8 degrees above the southern horizon. Saturn has just passed the meridian and is on the decline to setting. Jupiter, ahead of Saturn, is very low to the horizon and all too soon will be lost to view. Uranus is just below the eastern horizon but as the month progresses, will attain a good height in the dark sky. Neptune is above the horizon and rising higher in the sky. On the 23rd, Neptune is 3 degrees north of the Full Moon.

For those early-risers of you, the Winter constellations are rising and the constellation of Orion can be seen lying on his side just before dawn. Mercury can be seen very low in the east at 6am BST from the 5th as dawn begins to break. But BEWARE, THE SUN IS CLOSE, SO DO NOT POINT A TELESCOPE AT THE SUN AS YOU CAN VERY SERIOUSLY DAMAGE YOUR EYES! Instead, scan the east with binoculars to view the planet.
