Junocam captures stunning view of Io’s shadow during Jovian eclipse
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.
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.
Get ready for multiple shadow transits of Jupiter’s Galilean moons
Jupiter, the solar system’s largest planet, is now visible low in the southeast three hours after darkness falls in the UK. Now’s the time to dust off your telescope, check its optical alignment and hone your Jovian observing skills – particularly since a series of double shadow transits of the planet’s large Galilean moons starts on 24 March 2018.
See March’s multiple moon shadows and Jupiter’s Great Red Spot
If you haven’t done so already, now is the time to ensure that your telescope is clean and collimated (aligned) to deliver the sharpest images of planet Jupiter at its best. We tell you the optimal UK times to view the largest planet’s Great Red Spot and multiple shadow transits from its Galilean moons.
See the Moon’s close brush with Jupiter on the night of 27—28 January
Observers in the British Isles and western Europe with a clear sky low to the east around 10pm local time on Wednesday, 27 January can see the rising 18-day-old waning gibbous Moon in a close conjunction with Jupiter, the solar system’s largest planet. Jupiter draws steadily closer to Earth and grows in apparent size over the coming weeks.
