This beautiful picture of Jupiter with its Nice Crimson Spot (GRS) shortly after transit was captured by Christopher Go within the Philippines utilizing a Celestron C14 telescope and QHY 290M digicam on 22 June 2019 at 15:44 UT. Be aware the turbulence within the wake (left) of the GRS and the totally different look of the planet’s fundamental North and South Equatorial Belts. The GRS is seen in 7.6-cm (Three-inch) and bigger telescopes on nights of excellent seeing. North is up and celestial east is to the left. Picture credit score: Christopher Go.As June attracts to a detailed, largest planet Jupiter is an unmistakable magnitude -2.5 naked-eye object discovered highest within the southern sky of the British Isles near 11:30pm BST. By 13 July, when the planet lies near the 11-day-old Moon, the pair attain their peak altitude due south round 10:45pm BST.

Jupiter’s present location within the southern reaches of the constellation Ophiuchus does imply that the planet will get no greater than 14 levels above the southern horizon for an observer within the coronary heart of the UK, however on nights of calm air with good seeing there are nonetheless wonders to behold with telescopes of apertures as small as 7.6-cm (Three-inch) at magnifications of 100× or extra.

Nice Crimson Spot
Whereas Jupiter’s Nice Crimson Spot (GRS) seems to have briefly ceased its flaking exercise (see this story), observers ought to preserve a eager eye on this Earth-sized anticyclonic storm within the Jovian environment.

The desk on the backside of this web page lists the most effective occasions to see the GRS for observers within the British Isles and people components of Western Europe at the same longitude (e.g., Spain, Portugal, Central and Western France). For different areas worldwide, seek the advice of our interactive on-line Almanac, guaranteeing that the ‘Add phenomena of Jupiter?’ checkbox is ticked.

Jupiter’s moons
The most important planet all the time has extra to supply than cloud options in its continually churning environment. Jupiter is a veritable miniature photo voltaic system in its personal proper, with a household of 79 recognized pure satellites. The 4 giant Galilean moons — Io, Europa, Ganymede and Callisto — commonly go in entrance of (transit), are eclipsed (passing into shadow) or occulted (hidden) by Jupiter.Because of the present orbital inclination of Callisto to our line of sight, the outermost Galilean moon passes above or under Jupiter at conjunction. Observers within the UK can witness this (climate allowing) on Sunday, 14 July at 11:31pm BST when Callisto passes barely lower than four arcseconds south of Jupiter. Earlier this evening, don’t miss Io (left) rising from Jupiter’s shadow at 11:19pm BST. AN graphic by Ade Ashford.Io, Europa and Ganymede show transits, shadow transits (the place their shadows seem as inky black dots drifting throughout Jupiter’s cloud tops), eclipses and occultations all through July, as summarised for the British Isles and related longitudes within the desk under.Phenomena of Jupiter and its brilliant Galilean moons seen from the British Isles all through July 2019. Be aware that each one occasions are given in British Summer season Time (BST), so subtract one hour to transform to Common Time/GMT.
