Uh Oh! Must be all those accumulating Monoliths are beginning to have their affect. Just remember the warning: "ALL THESE WORLDS ARE YOURS, EXCEPT EUROPA, ATTEMPT NO LANDING THERE".

Here's what it'll look like by "2010" wink.gif

Yeah -- but in that case, who's down there painting them all red? Disgruntled natives?

Didn't mention this so far...



Does anyone know when both spots will reach the same longitude?

I hope this event will happen when NEW HORIZONS passes Jupiter next year...

Even if it's unlikely (due to their different latitudes), there is still the possibility of a merger of both spots... smile.gif

Bye.

That would be pretty interesting.
From what I can see Red Jr\Not So Great Red Spot appears to me to completely span (and disrupt) the South Temperate Zone almost extending into the South Tropical Zone and- at least according to the definitions on this http://jeff.medkeff.com/astro/observing/jov_nom/which explains the zone\band naming convention.
Using http://www.google.com/url?sa=t&ct=res&cd=8&url=http%3A//www.lpl.arizona.edu/%7Eshowman/publications/ingersolletal-2004.pdf&ei=y3YJRIWiPJeYQenq2dMO&sig2=7HW3i-F3ATux0wjKZOV-0g Ingersol et al 2004 as a source for the relative velocities of the various zones\bands.
My reading of the velocity\latitude chart in Fig 6.2 is that the GRS has an average eastward velocity of somewhere around -50 m/sec. This new storm should have a net eastward velocity somehwere in the region of 10-20m/sec. That difference is close to 250km/h
Eyeballing the two storms they _seem_ to me to be about 70 degrees apart - that's about 87,000km.
If all of the above is reasonable then they should coincide in around 14 days from the time the picture was
taken (Feb 27th) which would be March 13th.

Even if the above is grossly incorrect then I think that the differences in velocity of the two zones does mean that they will "coincide" pretty soon, and obviouly do so a number of times before NH arrives.

Posted by: stevesliva Mar 4 2006, 03:52 PM

It's interesting to read the the Great Red Spot is apparently less great and less red in recent decades. Could this be the end for the larger storm?

The appearance of two big red storms also makes me curious as to whether there are any gaps in the observational record that make the common "300 year old storm" assertion a stretch.

Pioneer 10 saw a similar smaller red spot during its historic flyby
in 1973.

Here is an image of it from the online NASA Pioneer Odyssey book:

Was this one seen from Earth as well at the time? I wonder what
the frequency of such storms are on Jupiter?

Photo in the News: Jupiter Spawns a New Red Spot

March 7, 2006—Look out, Great Red Spot. A brash young contender may be aiming for your title of Solar System's Most Powerful Storm.

NASA announced Friday that a new red spot has been born on Jupiter, as seen in a February 27 photograph (at top) by an amateur astronomer.

The new, formerly white spot—actually a storm named Oval BA—has been swirling since at least 2000 but acquired the familiar blushing tint of its centuries-old cousin only a few weeks ago. Nicknamed "Red, Jr.," Oval BA formed as three tempests gradually combined into a single superstorm, as seen in the bottom set of images.

So why are the storms red? No one really knows, but some scientists suggest that these miles-high vortices suck up material from lower altitudes. Once exposed to the sun's rays, the theory goes, the material reddens.

If you scroll down on their page to the April 12 and March 18 images of
Jupiter, you will see accompanying images of some of the Galilean moons.
They are good enough that some details can be seen on them. And Io
looks very orange red.

And go to his linked titled "My Best Images of Jupiter" and scroll to the

HUBBLE SNAPS BABY PICTURES OF JUPITER'S "RED SPOT JR."

NASA's Hubble Space Telescope is giving astronomers their most detailed
view yet of a second red spot emerging on Jupiter. For the first time in
history, astronomers have witnessed the birth of a new red spot on the
giant planet, which is located half a billion miles away. The storm is
roughly one-half the diameter of its bigger and legendary cousin, the
Great Red Spot. Researchers suggest that the new spot may be related to
a possible major climate change in Jupiter's atmosphere. These images
were taken with Hubble's Advanced Camera for Surveys on April 8 and 16,
2006.

To see and read more about the research on the Web, visit:

Right now, Jupiter is having a close encounter with Earth. The giant planet is very bright in the night sky and looks terrific through backyard telescopes.

Posted by: ugordan May 16 2006, 01:36 PM

While it is simply amazing that amateur astronomers nowadays produce better images than professional observatories did a couple of decades ago, I don't believe this trend will continue much longer by improving cameras and increasing telescope apertures. Even now, image quality is most strongly affected by atmospheric seeing and without adaptive optics, you can't squeeze out a much larger resolution, no matter how good equipment you have.
On the other hand, it'll be interesting to follow advances in adaptive optics over the years and how affordable they'll become to amateur guys. Check out http://planetary.org/blog/article/00000569/, there's a neat Keck montage showing just how AO improved in only 4 years. The next big quantum leap in amateur observing will surely come when (if?) AO becomes affordable. It's still best suited for infrared observations, though.

I can, or at least try to do rolleyes.gif : next steps will include the diffusion of Orthogonal Transfer CCD (like the ones developed for http://pan-starrs.ifa.hawaii.edu/public/design-features/cameras.html) which will reduce atmospheric blur through rapid pixels shift. And, on a longer period, perhaps the diffusion of simple, economic AO systems for evolved amateurs...

Perfect conditions at last! I finally have a decent image of the GRS and the Red Oval BA! Both spots are moving closer now for a conjunction around mid-July. Note the hint of the whirlpool vortex in the ring of the oval BA.

The NEB is very busy especially around the dark spot. And there is a weird feature on the NNTB at the CM where two dark barges are colliding?

edit- or at least-why is the one side white and the other orange?

Posted by: David Jun 28 2006, 06:33 PM

The band the LRS is travelling in seems to be entirely south of the GRS; I don't see why they shouldn't just pass by without much, if any, interaction.

Posted by: djellison Jun 28 2006, 06:38 PM

The expectation is that they'll just breeze past. There was an exhibition meeting of the BAA in Cambridge last weekend, and the director of the Jupiter Section showed images that demonstrate that new spot is getting darker and darker red over time, coinciding with it speeding up - and also, the GRS is getting smaller and lighter ( over the past century or so ) suggesting an opposite trend.

Posted by: dilo Jun 28 2006, 07:40 PM

Doug, are you talking about a possible passdown between the two spots? Would be great to see this, even if time scale of the two events (GRS fading and RSJr reddening) seems completely different...

Posted by: dilo Jul 4 2006, 05:50 AM

Now almost touching!

Posted by: PhilCo126 Feb 15 2007, 08:04 PM

So why are the storms red?
Scientists are still puzzled… sulfur, germanium oxide and various carbon compounds have been proposed as an explanation but the coloring agents still remain an enigma…

Posted by: ugordan Feb 16 2007, 04:47 PM

I'm curious: is the progenitor to Red Jr. the big, while oval that Cassini saw in 2000?
http://m1.freeshare.us/view/?128fs1460987.png
It certainly looks conspicuous. The funky composite is a MT3/MT2/UV1 as RGB. The oval appears bright in MT3 and very dark in UV so it turns out orange in the composite.

Posted by: elakdawalla Feb 16 2007, 05:25 PM

I've been trying to track down the origin of that storm too. Jupiter is hard because no cloud features stay put -- stuff at different latitudes shifts with respect to each other with timescales measured in days, and stuff at different longitudes but the same latitude shifts on slightly longer timescales.

According to some image captions on Photojournal the three white ovals first formed in the 1930s.

http://photojournal.jpl.nasa.gov/catalog/PIA00011, from July 1979. You can see three large white ovals of roughly equal size in the band just south of the Great Red Spot. One is just below the spot, the other two are some distance away.

http://hubblesite.org/newscenter/archive/releases/solar%20system/jupiter/1991/13/image/a/, with just one of the spots showing up. And http://hubblesite.org/newscenter/archive/releases/solar%20system/jupiter/1994/47/image/a/ in July 1994, where you can barely make out the positions of the white spots. They're much closer together than they were in 1979.

http://photojournal.jpl.nasa.gov/catalog/PIA01262 from February 1995. Three white ovals are now immediately adjacent. The caption says that the outer two white spots are ones that formed in the 1930s. What's the center one then? This caption also refers to another view from seven months earlier -- I haven't tracked that one down yet. There's http://hubblesite.org/newscenter/archive/releases/solar%20system/jupiter/1995/18/image/b/, but there's no caption information saying when it was taken.

Galileo was in position to witness their merger in February 1998 but was of course only able to return tight views. http://photojournal.jpl.nasa.gov/catalog/PIA01650 from February 1997 and September 1998. It says that two of the storms were called BC and DE after they formed. What was the third one called? What's the significance of these names? There's a whole bunch more of the February 1997 views http://photojournal.jpl.nasa.gov/catalog/PIA00700, http://photojournal.jpl.nasa.gov/catalog/PIA00873, http://photojournal.jpl.nasa.gov/catalog/PIA00872, http://photojournal.jpl.nasa.gov/catalog/PIA00871, and http://photojournal.jpl.nasa.gov/catalog/PIA00870...and 13 more...as well as a blinky http://photojournal.jpl.nasa.gov/catalog/PIA01231.

http://photojournal.jpl.nasa.gov/catalog/PIA02864, from October 2000. You see just the one oval, roughly 150 degrees of longitude away from the Great Red Spot. So, yes, ugordan, that's the progenitor to Little Red.

Somebody mis-natigated and a Vogon ship fullof RED NUMBER TWO collided with Jupiter.

Posted by: Bjorn Jonsson Feb 18 2007, 10:36 PM

The constantly changing appearance of Jupiter's atmosphere is a fascinating subject. Many of these changes are quite obvious in amateur astronomical telescopes once you are familiar with Jupiter.

The origin of this 'new' red spot can be traced back to 1939 when the three white ovals seen in the Voyager images started forming. They were formed as a result of changes in three separate locations in the South Temperate Zone. Originally they were very long but then steadily contracted, rapidly at first. They were extremely similar to the GRS. These three ovals were known as BC, DE and FA. As previously noted, originally they were very long. At that time they were separated by dark segments known as AB, CD and EF.

In 1998 ovals DE and BC merged into a single oval labeled BE. In March 2000 ovals BE and FA merged into a single white oval (oval BA) visible in the Cassini images. In 2005 this single surviving oval started changing color and in 2006 it had turned red. Interestingly, HST observations revealed that wind speeds in the spot increased after it turned red.

There is a huge amount of information on Jupiter's long term behavior in John Rogers' excellent book The Giant Planet Jupiter (to anyone interested in this subject: If you don't have it, get it!). Patrick Irwin's Giant Planets of Our Solar System discusses this in less detail but from a more technical perspective. There's also some information http://spaceflightnow.com/news/n0610/10jupiterspots/ and in particular http://www.redspotjr.com/.

Perhaps even more interestingly, the GRS may disappear in a few decades. It has been steadily contracting and if the same trend continues, by 2040 or so it will be circular. That's believed to be an unstable configuration so something interesting is going to happen - the big question is, exactly what?

Finally I'll end this by venting my frustration: I cannot observe Jupiter until 2010 due to my northerly latitude sad.gif.

Posted by: djellison Feb 18 2007, 11:21 PM

John is the BAA's Jupiter Section director - and I saw a great talk by him a while back where he suggested that the current GRS might not be the one that is supposed to have been visible for so long - but is actually the second GRS since recorded observations of Jupiter begun hundreds of years ago.

Also - the current spot is 'speeding up'. In 1950 it was rotating in around 10 to 12 days. Now it's more like 4 - 6 days - but at the same time it's getting smaller so one can't assume it's getting faster as a result

Observations of Jupiter are one of the great amateur projects still ongoing.

Posted by: nprev Feb 18 2007, 11:54 PM

Fascinating idea that this might not be Galileo's GRS...but if you think about it this makes sense. Jupiter's atmosphere is so dynamic that it's ridiculous to think of the GRS as a permanent feature in terms of geological time.

I recall some simulations a few years ago that indicated that a Spot-like storm almost always arose given a Jovian planet's assumed atmospheric properties, rotation rate, etc. But, it apparently doesn't have to be the same Spot every time. My question is whether two or more of similar magnitudes could be sustained, or does one have to die before another can fully form? huh.gif

James Gleick's book Chaos referenced a http://www.nature.com/nature/journal/v331/n6158/abs/331693a0.html that showed how a GRS would appear on Jupiter. The photos from the book are amongst http://www.me.berkeley.edu/cfd/videos.htm. There are some pretty neat videos there.

It is hard to tell. Before the early-mid nineteenth centuries, observations of sufficient quailty, both in terms of accuracy of the drawing and quality of the telescope, are spotty. But it is clear that the GRS is far from its former glory. For example, in this 1879 photograph by A. Common, the spot has the long appearance it had for the Pioneers, but, based on photos like this and visual observations, it was twice the size. The fact that the film used was sensitive to deep blue light jacked up the contrast, something I tro compensate for.

I'm always suspicious of modeling results that predict the past, but they're an interesting start towards science. Note that Saturn doesn't have a great red spot, and it's pretty similar to Jupiter. Also note that Jupiter's northern hemisphere doesn't have a great red spot.

There's more than one Internet kook who insists that the GRS reflects phenomena taking place at/in Jupiter's solid core, rather than being purely a fluid dynamic phenomenon in the upper atmosphere. While it's kooky to insist so, it's an interesting conjecture. It would certainly be nice to know more about the inner 50% of Jupiter, and Juno should be an exciting mission and would be even if it had no camera at all.
