So-called “brown barges” are cyclonic storms in Jupiter’s atmosphere that are typically found in the giant planet’s relatively dark North Equatorial Belt but they are occasionally spotted om the South Equatorial Belt as well. The storms are difficult to detect visually because they tend to blend in with the surrounding areas. But occasionally, the darker material in the belt recedes and brown barges become easier to see against the lighter background. This image, capturing a brown barge in the South Equatorial Belt, was captured by NASA’s Juno Jupiter orbiter on 6 September as the probe made its 15th close flyby at a distance of 11,950 kilometres (7,425 miles) from Jupiter’s cloudtops. The color-enhanced JunoCam image was processed by citizen-scientist Kevin M. Gill.
Some of the world’s leading amateur and professional astronomers are meeting on 12-13 May to prepare for a campaign of ground-based global observations in support of NASA’s Juno mission to Jupiter. Delegates from 13 countries in Europe and around the world are meeting at the Observatoire de la Côte d’Azur in Nice, France.
Jupiter is now less than a month from opposition (7 April), so it’s very much open season for the Solar System’s largest planet. If you’re unsure where to find it, the rising 17-day-old waning gibbous Moon passes just two degrees from Jupiter on the UK evening of 14 March. Virgo’s brightest star, first-magnitude Spica, makes it a great binocular triumvirate.
