¤·····Subject: A discovery about Saturn

Received; 29 June 2013 at 13:54 JST

 

Hi everyone,

I was looking at my Saturn images from 2006. Then I saw the
South Polar Region was olive green colored and hexagon-shaped like the current 2013 North Polar Region!! Apparently at the time no one noticed it.

 

See Saturn images I've notified Julius Benton ALPO Saturn coordinator. You might want to check your archives and see how far back the SPR was hexagon shaped. I'd like to know what you find. Thanks.

 

Good seeing,

Received; 27 June 2013 at 09:48 JST

 

June 26, 2013

Dear Friends and Colleagues,

Just a moment ago, we launched a new website that is intended to be the
portal to all things associated with the upcoming July 19 Earth-imaging
event called The Day The Earth Smiled.

Visit ...

            
http://TheDayTheEarthSmiled.com


... and you will see how we expect things to unfold, which organization
are providing coordination services for events being planned around the
globe, and what projects are already underway.

Also on this site, you will run across a link to the two global
competitions that my company, Diamond Sky Productions, is running in
association with July 19.   These are contests requesting submissions of
contributions -- images in one case and musical compositions in another
-- from members of the public.

*Of particular note*:  The winning entry in the image contest will be
included in a digitally encoded message that will be beamed, at some
future date, to space from a large radio antenna on Earth on either the
first, or second, anniversary of July 19, depending how things go,   In
this message, we will announce our presence to the Milky Way and
describe us and our planet.  It's only been done seriously once a long
time ago.  We aim to do it again, only better.

I am proud to say I am joined in all this by an impressive set of advisors.

Check out the RECENT page at ...


        
http://diamondskyproductions.com

... and have a look, especially in the Advisor section.  Can't go wrong
with that lineup!

And that's it for now.

Wish us luck, and I hope our camera at Saturn finds you smiling at the
appropriate time on July 19.

Enjoy!

Hi
I was imaging AR1775 and managed to grab an area close to it where the seeing held reasonable for 50 minutes from
07:49 to 08:39UT. I did get 2 hours but last hour was hopeless seeing. Here is the result at 4m focal length and image scale increased x 3. Has to shoot 2,000 to 3,000 frames every two minutes to get some reasonable ones stacked best 400. The AR gif has a 2 x image scale increase.

 


Hope this is of interest.

Here is another Saturn image from the reasonable seeing of 2nd June this time with my DMK mono camera and with the coloured images combined in Winjupos. Certainly the image is more colourful with the mono imaging than with the colour ASI120MC camera but not sure there is any more detail. Colour camera was about 5x quicker to process to a finished image!

Received; 19 June 2013 at 04:35 JST

 

June 18, 2013

Dear Friends and Colleagues,

Something great, something big, something very special that's never happened before is about to happen!

On July 19, 2013, NASAfs Cassini spacecraft will be turned to image Saturn and its entire ring system during a total eclipse of the sun, as it has done twice before during its previous 9 years in orbit.

But this time will be very different. This time, the images to be collected will capture, in natural color, a glimpse of our own planet
next to Saturn and its rings on a day that will be the first time Earthlings know in advance their picture will be taken from a billion
miles away.

It will be a day for people all over the globe to celebrate together the extraordinary achievements that have made such an interplanetary photo session possible. And it will be a day to celebrate life on the Pale Blue Dot.

A new Captain's Log that expresses the significance of this event and how you can participate in it can be found in the usual place on ...

http://ciclops.org

You can also find graphics showing where Earth will be relative to Saturn and what portion of the Earth will be illuminated during the picture-taking event at ...

http://ciclops.org/view_event/193/

Our planet, of course, will only be a blue point of light as seen from Saturn. But it, and we, are unique in all the solar system, and that is worth celebrating!

CASSINI IMAGING LEAD HOPES FOR PLANET-WIDE CELEBRATION OF THE PALE BLUE DOT

On July 19, 2013, NASA's Cassini spacecraft will be turned to image Saturn and its entire ring system during a total eclipse of the sun, as it has done twice before during its previous 9 years in orbit. But this time, the images that will be collected have been specifically designed for something very special. They will capture, in natural color, a glimpse of our own planet next to Saturn and its rings, during an event that will be the first time Earthlings know in advance their picture will be taken from a billion miles away.

'It will be a day', says Cassini imaging team leader, Carolyn Porco of the Space Science Institute in
Boulder Colorado, 'for all the world to celebrate.'

'Ever since we caught sight of the Earth among the rings of Saturn in September
2006 in a mosaic that has become one of Cassini's most beloved images, I have wanted to do it all over again, only better', said Porco. 'And this time, I wanted to turn the entire event into an opportunity for everyone around the globe, at the same time, to savor the uniqueness of our beautiful blue-ocean planet and the preciousness of the life on it.' Porco was involved in co-initiating and executing the famous "Pale Blue Dot" image of Earth taken by NASA's Voyager 1 from beyond the orbit of Neptune in 1990.

"While Earth will be only about a pixel in size from Cassini's vantage point 898 million miles [1.44 billion kilometers] away, the Cassini team is looking forward to giving the world a chance to see what their home looks like from Saturn," said Linda Spilker, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "With this advance notice, we hope you'll join us in waving at Saturn from Earth, so we can commemorate this special opportunity."

The intent for the upcoming mosaic is to capture the whole scene, Earth and Saturn's rings from one end to the other, in those particular camera filters - red, green and blue -- that can be composited to form a natural color view, or what human eyes might see at Saturn. It also includes imaging the Earth and the Moon with the high resolution camera, something not yet done by Cassini.

Three years ago, Porco and her staff members at CICLOPS began carefully examining Cassini's planned trajectory for the remainder of its Saturn mission in search of the best time to image the Earth when it was unobstructed by Saturn or its rings, and when there weren't other pressing scientific observations that rendered the idea impossible. Imaging any planetary body close to the sun necessitates doing so when the sun is completely blocked, so that no undiluted sunlight can enter the cameras or other Cassini instruments and damage their sensitive detectors. Such opportunities during Cassini's orbital tour are rare.

When all was considered, the best time for this event was found on
July 19, 2013. For several hours on that day, the spacecraft was once again going to be in Saturn's shadow as a result of the planning work of the project's rings working group and the spacecraft team. The intent was to duplicate the eclipse geometries from earlier in the mission to collect, for scientific purposes, both visible and infrared imagery of the planet and its ring system.

Grabbing the chance to image the Earth within the mosaic of scientific images already being planned by both the imaging and infrared mapping teams involved special care and a lot of work to ensure a mosaic without gaps and an unobscured image of the Earth without the overwhelming glare from nearby rings.

It was a big challenge and turned into a fine example of teamwork.

'My colleagues on the VIMS team were great sports about it, and allowed us to tweak their mosaic to find the best placement of mosaic images and the best times for the high resolution Earth images', said Porco. 'In the end, we all got what we wanted.' Unlike previous images of Earth by NASA interplanetary spacecraft since the days of Voyager, this will be the first time that the world's people will know ahead of time that their picture is being taken.

Porco is hoping for a memorable event.

'My sincere wish is that people the world over stop what they're doing at the time the Earth picture is taken to revel in the sheer wonder of simply being alive on a pale blue dot of a planet, and to appreciate the ever-widening perspective of ourselves and our world that we have gained from our interplanetary explorations. We are dreamers, thinkers, and explorers, inhabiting one achingly beautiful planet, yearning for the sublime, and capable of the magnificent. Let's celebrate that, and make this one day a day the whole Earth smiles in unison.'

Cassini's images of Earth, both wide angle and narrow angle, will be captured between
21:27 to 21:42 on July 19 UTC, or 14:27 and 14:42 PDT. During these times, North America and part of the Atlantic ocean will be in sunlight. The illuminated parts of the Earth and the Moon will each be no more than one pixel across.

Graphics illustrating the position of Earth with respect to Saturn and its rings, and the part of the Earth viewable during this event are available at http://www.ciclops.org/view_event/193/ ,

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory (JPL), a division of the California Institute of Technology in
Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team consists of scientists from the U.S., England, France, and Germany. The
imaging operations center and team leader (Dr. C. Porco) are based at the Space Science Institute in
Boulder, Colo.

It was a great pleasure for us to finally meet you in person in Paris! And we can never thank you enough for giving us a privilege of visiting the Sorbonne observatory, the beautiful 15cm refractor dome, and the optical workshop of the SAF which must not  usually be opened to the public.
When I was home, I found your opening essay for CMO#411 has already reached me,  I'll be starting on a translation of it soon.

Dear Christophe,

I heard from Rei-ichi just before he departed to Paris that he and his better-half were going to meet you on 15 June at St-Michel somewhere. I hope you will enjoy a nice rendezvous with them. I suppose they at present are spending their times in visiting many splendid Art Museums in Paris. Especially I hear his wife is fond of arts.

By the way, I hope you are preparing an opening essay for #411 about the pro/ama collaboration in planetary observations. Officially its dead line is within 15 June. I expect we will receive your interesting essay with some photographs soon. I have just begun to make a layout of #411.

Here in Japan it has become warmer. I disliked the cold situation especially this winter, and so it is better for me. However I have a trouble on my right-eye; maybe I am losing it.

Thank you very much for your kind collaboration concerning the CMO.
With best wishes

Hi all,

I spent some time yesterday working on extra noise reduction in some of my processing with the new ASI camera - it has appreciably more noise than my other cameras and can benefit from more pop-filter style processing. Here is an extra RGB image from June 4 with the new filtering, this data was not originally processed since it did not correspond to a longitude where the interesting things are happening, but the image quality was quite good nonetheless.

Hi Guys,  Here are a few offerings from the past week . Saturn in poor seeing here is simply a record of colour and shadow but was still enjoyable to capture.  The solar images are off my old Skynyx as my flea's express card has failed and I 'm awaiting a new one. Time for USB3 CMOS I wonder ?   

 

The skynix chip is is bigger than the flea's so the mag is a bit lower on the 3rd with my normal set-up. For the images on the 4th I played around with Barlows various, which has puffed the plasma clouds up somewhat.  I wish Televue made a 3x constant mag powermate.

Hi all,

Some quite good seeing for a while last night, until the fog rolled in... one of the winter hazards around here.

Two images here, one IR and one RGB. They both show the long lived dark spot, sown enhanced in insets on both images, as well as the polar hex. The colours in the RGB image are interesting, the polar region continues to change colour slowly as the apparition progresses. The polar region outside the hex that was light green a few months ago is now a distinct yellow.

 

Both images have been derotated using WinJupos and are the combination of several individual data sets.

cheers,

Subject: L. Elpidio Lopez

Dear Dr. Sheehan,

This is a long shot, but I thought I'd give it a try. Many years ago  the late Charles "Chick" Capen suggested Elpidio L. Lopez as a name for a crater on Mars. I have never been able to find published biographical information about Lopez, a requirement for our IAU database. He seems best known for his book "El Planeta Marte: 1907-1956" published in 1963 by Imprenta Aldina, Mexico, D.F. However, that is all I have found about him.

Might you know of any biographical information about him? Chick Capen was a close friend of mine (an excellent visual observer of Mars himself) and apparently thought very highly of Lopez.

Many thanks for any help you might be able to provide.
