More Jupiter events to enjoy in August 2019
Jupiter is two months past opposition on 10 August, so you need to be looking low in the southern sky of the British Isles around sunset if you wish to catch the solar system’s largest planet at its best. If you time it right and the weather obliges, Jupiter’s Great Red Spot makes multiple appearances while the planet’s Galilean moons play hide and seek. Welcome to our August 2019 Jovian observing guide.

See the International Space Station above the eclipsed Moon on 16 July
The serene beauty of the International Space Station gliding silently across the sky needs nothing more than the naked eye to appreciate. But when the dazzling ISS is also in conjunction with a partially eclipsed Moon, Saturn and Jupiter on the 50th anniversary of Apollo 11’s launch, be sure to look low in the southeast through south around 10:06pm BST on 16 July 2019!

See ringed planet Saturn at its best in July 2019
Observers in Western Europe with a clear sky around local midnight cannot fail to notice the conspicuous ‘star’ that is Jupiter low in the south. But look a span-and-a-half of an outstretched hand at arm’s length to Jupiter’s left and you’ll find another giant of the solar system – Saturn. The ringed planet is closest to Earth for 2019 on 9 July, so here is our quick observing guide.

Further Jupiter events for UK observers in July 2019
July opens with Jupiter three weeks after opposition, but the largest planet is still putting on a fine show as an unmistakable magnitude -2.6 object low in the south before midnight in the constellation of Ophiuchus (the Serpent Bearer). With ongoing developments in the Jupiter’s Great Red Spot and plenty of phenomena occurring with the planet’s large Galilean moons, here’s our Jovian observing guide for July 2019.

Don’t miss Jupiter’s ‘unravelling’ Great Red Spot
The Great Red Spot (GRS) is the solar system’s largest known storm, an Earth-sized anticyclone that has raged in the atmosphere of Jupiter for at least two centuries. But recent observations from Earth and space suggest that this iconic Jovian feature is undergoing huge changes that could herald its demise.

Get ready for prime-time Jupiter and its multi-moon events in June 2019
Jupiter, the solar system’s largest planet, reaches opposition on 10 June in the constellation of Ophiuchus (the Serpent Bearer) and is visible low in the southern sky of the UK through the night. Observers with small to medium aperture telescopes can see a number of shadow transits of Jupiter’s Galilean moons and view the planet’s Great Red Spot throughout June.
Observing
See the Moon and Jupiter get close in the small hours of 21 May
Observers in the UK with clear skies around 1am BST on Tuesday, 21 May can see Jupiter, the solar system’s largest planet, just 4 degrees from the waning gibbous Moon low in the south-southeast. At this time both the Moon and Jupiter fit within the same field of view of binoculars magnifying less than 10×, while telescope users can also view Jupiter’s Great Red Spot.
