Saturn is in opposition
Saturn is on the ‘opposite’ side of the sky to the Sun – when the Sun sets in the west, Saturn appears in the east.

Saturn is approaching opposition on 21 September 2025, which is the best time to see the planet, when it will be its biggest and brightest.
o
Over the coming weeks, as the Moon begins to wane and moves out of the way, there’ll be a great opportunity to get out your binoculars or telescope and see Saturn at its best.

Occultation of Venus by the Moon

The Moon occults the planet Venus on 19 September,
this will be under full daylight, but
magnitude –3.8 Venus will still be visible.

(Click below for enlarge)

The Moon’s position in the sky changes depending on where you are on Earth. An occultation is a very localised event, meaning it can only be seen from a certain path or region on Earth where the Moon happens to block Venus for the observer.

Mercury will reach its superior conjunction, meaning it will be on the far side of the Sun from earth and therefore cannot seen.
o
 At this point, Mercury will move from the morning sky to the evening sky, but it will remain hidden in the Sun’s glare for the rest of the month, making it invisible to observers in the UK – next visible in October in the evening sky.

Tonight’s sky over the UK is serving up a great pairing of bright Moon & Saturn, both visible all the night sky.

From 22:00 / 10pm onwards, when they are high enough for clear viewing – this alignment is perfect for outreach and bright enough for binoculars.

Some of our deaf astronomers and friends all over the UK – I received too many text as they were delighted and excited to witness pop out and look to the Moon but some of them were gutted due the clouds obstructed.

One of them from Berkshire Deaf Astronomical Society was sent me her photo of Partial eclipsed – fabulous!, that they witnessed it! – see below, and far below the clouds managed to clear up I was just in time to get this photo.

The sky did finally clear, but it was way too late for the shot – a reddish of Total Lunar Moon, we had lined up, but there was a little bit of the partial eclipse left.

Close approach of the Moon and Saturn

• The Moon will pass close to Saturn on the nights of Sunday 5th and Monday 6th October 2025, with their closest approach occurring late on the 5th October.

• Saturn, with its iconic rings, is one of the brightest planets visible to the naked eye.
  o
• When it appears next to the Moon, it’s easy to spot and makes for a stunning sight.
  o
• You can see them without a telescope, though binoculars or a scope will enhance the view.
