WOW! |

Just think what we might have seen IF Galileo's main antenna hadn't got stuck. Some more tears shed here. -------------------- Antti Kuosmanen

Neat image of Io being occulted by Jupiter. Edge of Tvashtar's plume visible at the top.

I hadn't realized that was a Jupiter occultation -- just thought it was subframed for some reason. Now I can see the disk, and realize from the exposure time of 100 ms that the surface of Io is lit by Jupitershine. That is a cool picture!

What a movie! Together with the dust devil movies on Mars they remind me that the Earth is not the only active place in the solar system.
Enthusiasm + good planning + a bit of luck = awesome movie |

That is a cool picture! --Emily Note the plume mirage too- the short streak extending from the edge of Io's disk along the limb is an image of the Tvashtar plume, distorted by refraction in Jupiter's atmosphere.

Wow - I've just gone back and read the first reply I made to the Kodak Moment 'RFP' from last year - and it was something similar - glad to see I wasn't entirely wrong about the atmospheric effects

As we more and more crescent views come down, be on the look out for faint plumes:
Here is a list of plumes from NH thus far: CODE Name Lat Lon Masubi (north) -45 53 Masubi (south) -49 58 Zal Patera 41 75 Amirani 23 116 Tvashtar Paterae 63 123 Prometheus 1 153 Culann Patera -20 162 Illyrikon Regio -70 170 Marduk -28 210 Kurdalagon Patera -50 218 Hephaestus Patera 2 290 N.

I like your new avatar, volcanopele!

I'm blown away, seeing that plume rising above the edge of Io, to me, is the most dramatic picture I've seen since those first pictures from Huygens. Seeing the glowing eruptions on the night side of Io during an eclipse, simply breathtaking.
Absolutely remarkable, and all from a flyby! -------------------- Turn the middle side topwise....TOPWISE!!

A nice series of pictures just added to the SOC site, showing the night side of Io just beside the limb of Jupiter

Here is another cool one:
http://pluto.jhuapl.edu/soc/view_obs.php?i...osure=93%20msec Obviously the Tvashtar plume is quite prominent at upper right. You can also see the Prometheus plume on the dark limb at center right and the plume over the northern Lerna Regio eruption near the terminator at bottom. Also near the limb you can see the bright material surrounding Ra Patera and "Carancho Montes", an 8-km tall mountain chain northeast of Ra Patera. -------------------- &@^^!% Jim!

Bellissime, Paolo!
The 3 exposures are taken with increasing integration time, only in the first one Jupiter is not oversaturated (...solarized!? ). Here I crudely merged the first and the last in order to have a "High Dinamic Range" image (Io details are enhanced): Something in this image is a Deją Vue... -------------------- I always think before posting! - Marco -
