Jupiter heeft een streep minder!

Is er echt helemaal niks bekend over waarom dit gebeurt? De rode vlek lijkt er nog wel te zijn, dus de lagere luchtlagen zijn dan nog wel rood?

AMAZING IMAGE OF JUPITER:
Last night, the atmosphere over Australia settled into a state of rare, crystal-clear transparency -- and it did so directly above the observatory of world-famous astrophotographer Anthony Wesley. The result was a picture of Jupiter that some onlookers are calling the finest-ever by an amateur astronomer. "On a scale of 1 to 10, the seeing was a 12," says Wesley. "Now I know what it must be like to see the giant planet from space."

Hij verliest en krijgt er weer een bij ongeveer elke 15-20 jaar.
Waarom dit precies gebeurt is volgens mij niet bekend.

JUPITER'S MISSING STRIPE, RETURNING?

Earlier this year when Jupiter's great South Equatorial Belt (SEB) vanished, researchers urged amateur astronomers to be alert for its eventual return. The SEB had come and gone before, they noted, and the revival was something to behold. Alert: It might be happening now. After months of quiet in Jupiter's south equatorial zone, a white plume is surging through the cloudtops where the SEB should be. Christopher Go of the Philippines took this picture on Nov. 9th:



It might not look like much, but this is how a revival of the SEB begins--a small disturbance in the upper atmosphere heralds a much larger profusion of spots and swirls bursting forth around the whole circumference of the giant planet. Amid the confusion, Jupiter's vast brown stripe emerges.

Subsequent observations by astronomers in the United States, Japan, and the Philippines not only confirm the plume, but also show it brightening rapidly. Indeed, as Nov. 11th unfolds, it is the single brightest spot on Jupiter in wavebands ranging from infrared to ultraviolet.

"This plume is so energetic that we can confidently expect it to develop into the SEB Revival," says John Rogers, director of the Jupiter section of the British Astronomical Association. "The SEB Revival is usually spectacular, so we can expect impressive and rapidly changing disturbances over the next 3 months."

Experienced planetary photographers are encouraged to monitor developments. If events proceed apace, the Revival could become visible to novices using small backyard telescopes, so stay tuned.

Dat vraag ik me net ook af.

En ik ook! Snap niet hoe ik dit gemist heb...

Die aliens daar hebben gewoon de fabriek tijdelijk stopgezet om periodiek onderhoud te plegen. Vandaar geen rook meer.

Als die fabriek niet geraakt is door die meteoriet uiteraard.

Misschien een soort van inversie-laag doorbroken, waardoor er een enorme supercell onstaan is op Jupiter.

Ik vraag me af of daar ook onweer op gaat zitten. (er werden al ooit bliksemflitsen waargenomen op Jupiter)

REVIVAL ON JUPITER:
Think of the turmoil at the sea surface just before a massive submarine emerges from depth. Something like that is happening on Jupiter. A turbulent plume is breaking through the giant planet's cloudtops in the south equatorial zone, heralding the emergence of ... what? Scroll past this Nov. 14th photo from astrophotographer Paul Haese of Glenalta, South Australia for further discussion:



The plume, circled in Haese's photo and known to astronomers as the "SEB Revival Spot," is a sign that Jupiter's South Equatorial Belt (SEB) is about to return. The great brown belt disappeared earlier this year, leaving Jupiter without one of its signature stripes. No one knows where the SEB went, although some researchers have speculated that it sank beneath high altitude clouds and might now be bobbing back to the top.

Christopher Go of the Philippines first noticed the Revival Spot on Nov. 9th. At first it was small and white and required careful astrophotography to detect. Only five days later, it is expanding rapidly and darkening; soon, it could become visible to novices in the eyepieces of backyard telescopes. Stay tuned for updates.

OUTBREAK ON JUPITER:



The return of Jupiter's lost stripe (the South Equatorial Belt) is proceeding apace. At least three energetic plumes are breaking through the cloudtops of Jupiter's south equatorial zone, shown here in a weekend photo from Brian Combs of Buena Vista, Georgia. Researchers believe these plumes herald the emergence of the globe-straddling belt, mysteriously absent for nearly a year.

Wtf, bizar ding.

Erg bijzonder en apart...

Jupiter krijgt zijn streep terug

AMSTERDAM - Dit voorjaar verdween een van de opvallende donkere wolkenbanden in de atmosfeer van Jupiter. Nieuwe NASA-opnamen wijzen erop dat de band zich aan het herstellen is.

Begin november ontdekte een Filippijnse amateurastronoom een opvallend heldere plek op de plaats waar normaal gesproken de zuidelijke equatoriale wolkenband van Jupiter te vinden is.

Volgens Amerikaanse astronomen is dat het begin van het herstel van de donkere streep die doorgaans ten zuiden van evenaar van de planeet te vinden is. De oorzaak van het verdwijnen van de wolkenband lijkt te liggen bij het tijdelijk wegvallen van de droge valwinden die het betreffende gebied vrijhouden van hoge, heldere wolken van ammoniakijs.

Hierdoor werd de lager gelegen donkere wolkenband tijdelijk aan het zicht onttrokken. Het was niet voor het eerst dat dit gebeurde. Zo eens in de paar decennia herhaalt de zuidelijke equatoriale band - en alleen díé - dit kunstje. Naar de oorzaak van deze abrupte verandering wordt nog gezocht.

Schitterend he? It is back.

RETURN OF JUPITER'S MISSING STRIPE:
The revival of Jupiter's South Equatorial Belt (SEB), missing for nearly a year, is now well underway. The roiling, turbulent disturbance that heralds the brown stripe's full return stretches almost halfway around the giant planet. "Here is a projection map showing the revival on Nov. 29th," says amateur astronomer Wayne Jaeschke of West Chester, Pennsylvania. Note the region bracketed by arrows:


_{Here is a projection map showing the revival of Jupiter's SEB, about three weeks after it began. The map is made from two frames RGB images taken about 50 minutes apart on Nov. 29 at 00:33 - 1:20 ut in pretty good seeing.}

"I made the map by combining two pictures of Jupiter I took using my 14-inch Celestron telescope," says Jaeschke. "The disturbance has grown dramatically since it first appeared in late October." Indeed, it is now so large that even novice observers are starting to notice it in the eyepieces of backyard telescopes.

The spreading disturbance is not the SEB itself. Instead, it is thought to be a progressive clearing of high clouds that will eventually reveal the brown stripe hiding below. When the SEB finally returns, Jupiter will have two brown stripes again and the planet's appearance will return to normal. Meanwhile, amateur astronomers are encouraged to monitor the revival.
