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 Emily's blog on Uranus' equinox, 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. -------------------- |

less than 2 months to collision??? Maybe this is one way how the Great Red Spot has remained active and huge for centuries, by absorbing smaller storms? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

It amazes me how much amateur observations have increased in clarity. I can't even imagine what the next 10 years brings! I can, or at least try to do : next steps will include the diffusion of Orthogonal Transfer CCD (like the ones developed for PanStarrs project) 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... -------------------- I always think before posting! - Marco -

The two spots are even closer now, look to Christopher Go site. He say:
QUOTE May 28, 2006
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? More images later as I am still processing about 15Gb of data!! -------------------- I always think before posting! - Marco -

NASA Science News for June 5, 2006
The two biggest storms in the solar system are about to go bump in the night, in plain view of backyard telescopes. FULL STORY at http://science.nasa.gov/headlines/y2006/05....htm?list161084 -------------------- "After having some business dealings with men, I am occasionally chagrined,

closer and closer:
all images were taken from Christopher Go site. Note also images reported in the other site dedicated to red spot, is incredible to see surface features on some galileian satellites from amateurs! -------------------- I always think before posting! - Marco -

I hope that WFPC2 on Hubble is still working fine, unlike ACS and that they are planing to use it to observe this close encounter event...

is it just me or is the spot turning the white band orange?
edit- or at least-why is the one side white and the other orange? |

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.

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.

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...

Now almost touching!
Christopher Go comments is:"The GRS and Oval BA are very close now. From the looks of it both storms will just pass by! There is enough clearance between the two storms" -------------------- I always think before posting! - Marco -
