Hi all,

Again a spoke visible over Ring B (see RGB image and animation, also the second BP642 series), and various white patches (one of them might Enceladus in transit over the southern hemisphere)

Regards,

Hello Tom, hello all,

 

>Ring A is translucent, and a very bright spot on the globe may be visible through it.

 

Yes indeed it must be the answer... and by the way, I have forgotten, but it's very likely to be the spot I imaged myself (!) at the AstroQueyras observatory just one month before (when the rings were less opened) :

Hello Christophe. Sean Walker forwarded your message about the remarkable feature recorded by Fremond. There can certainly be little doubt that this feature is real, but is it located in Ring A?

 

During the 77 minutes that elapsed from the first to the last images in the video, the displacement of the feature does not seem to correspond to the orbital motion of an object in Ring A (13.2 hours for an object in the center of that ring). After carefully reviewing the video many times, to my eye the feature is not rotating perceptibly slower than the bright spot at a high latitude on the globe. On the contrary, it seems to be moving slightly more rapidly than that feature. This suggests that it is not located in Ring A but rather on the globe.

 

If I may speculate... Ring A is translucent, and a very bright spot on the globe may be visible through it. We are overdue for a Great White Spot, which first manifest as brilliant "pearls." 

 

Kind regards,

 

Tom DOBBINS (Howard,OH)

Hi Anthony, many thanks, I have just found Trevor's observation from the 12th, where a bright spot is visible juuust below the rings indeed, and within 10° of longitude in system I. With a lower resolution it could give the impression it is visible through the A ring...

Hi Christophe, there has been a bright storm visible in Saturns south for a while now, it has been seen just below the ring plane roughly where this bright spot is seen but with the rings now slightly more open at this time it's possible that this storm is being seen through one of the gaps, maybe through the Cassini Divison, or it's still being seen just under the edge of the ring.

You can see the other bright storm close to the south pole in the same animation you link here and it's clear by watching the pair of them that they are both in Saturns atmosphere and not in the ring.

cheers,

Hi all,

A french observer recently observed a very curious feature rotating inside the A ring of Saturn on Sept. 13th, in front of the globe.

The animation he made lets little room for doubt. Yet I have never heard of such a thing ?

Spokes are not supposed to appear there, and not supposed to be bright as seen from Earth, so it might be something else.

(a southern bright spot can be seen as well)

 

I began my own observations that night just 10 mn after his sequence, under good conditions, but I have nothing (although I did imaged some real spokes later that night)

Hi all,

Here are some images taken under good seeing, with the GRS and Callisto.

It looks to be slightly less colored than last year, judging by its aspect in B and UV.

Christophe

Hi all, here's an image of Saturn from last night using a 600nm longpass filter.

Seeing was better than average for here at present and it was possible to detect the faint remnant of the great storm of 2010 which Trevor has been tracking.

Hi all,

Some image taken through a good layer of Saharian dust flying over western France...

Seeing was good but the low transparency degraded the resolution.

Hi all,

Those are the last Jupiter images, taken during the first good night. There have been a serious degradation in the seeing though, that slowly recovered up to sunset. A good IR image was taken then, while previously many B and UV filters were used.

 

 


 


 


 

 

I am adding photometric profiles of the B and UV NEB. Our eyes don't see how strong is the gradient of light from the limb to the terminator. Usually the shape of the profile is a bell with the maximum of intensity aiming at the Sun (the difference from the central meridian calculates the "Solar angle").

 


 

While the bell shape is still visible on the NEB in blue light, it disappears in UV where the limb is the brightest part (and the whole shape is more squared).

This reveals the presence of high-altitude hazes in the UV image that are not detected in blue light since those hazes are more thick looking toward the edges of the disk, where they are going to scatter and reflect more light.

Hi all, here's an image of Saturn through a 600nm longpass filter from last night.

I captured 12 runs over a period of 30 minutes in early evening while Saturn was still quite low in the east and the seeing was relatively stable.

There doesn't seem to be much activity on this longitude.

By 9pm local time the seeing was very poor and no more data could be recorded.

 

All the best
