Hi all,

Here is again my full spectrum of Uranus, with a different processing. The results are now obtained with ISIS and Gnuplot, which gives a synthetic colorisation that I prefer.

The first serie is the same at the one previously sent, and represents the pure capacity of the planet to reflect the sunlight (the reflectance).

For the second serie I divided the raw Uranus spectrum by the instrument response, calculated on an adjacent star (the same, actually, but this is not important there). This serie now reveals the real color response of the planet. As the reflectance shows Uranus almost perfectly reflects light in the deep blue, the blue end is now similar to the Sun spectrum.

 


 

Best regards and may you all have nice end of year celebrations.

¤·····Subject: Full Uranus spectrum with IR, 2018/12/09

Received: 17 December 2018 at 20:30 JST

 

Hi all,

Here is a new experience on Uranus spectroscopy. For this time, I took a second spectrum for both Uranus and the reference star with an infrared filter (Baader IR685) and then assembled the two cuts (visible+IR) under Vspec to get a full spectrum up to the infrared end.

 

This is necessary since with the SA100, the blue end of the second order is overlapping with the IR end of the 1st order, as a result the data after 750 nm is mixed and not exploitable. Using a filter of order allows to get a pure IR spectrum, and because exposure time is higher, allows a correct recording of the very faint Uranus features. As a result the greatt 890 nm CH4 band and the last continuum at 940 nm are clearly showing.

 

Processing is done by diving raw Uranus spectra by raw G2V spectra. Overlapping zone between the two cuts is 700-710 nm. Offset, dark, flat corrected and skybackground removed during IRIS processing.

 

More experiences when clouds go away!

 


 

Best regards

Dear all,

Two acquisitions of Mars from July 14 by myself and Christoffer Svenske, at a time when the dust storm raged and contrast was very low.

One image is with a 290MM camera RGB+742 filter, the other with a DBK21AU618 camera RGB. Obtained from Tenerife.

Visually, only the two or three darkest parts of the albedo features, and the northern limb haze, could be glimpsed.

I am still seeing a similar effect at the SPC that I saw on 11 Dec(possible G/B extension beyond limb), but to a lesser extent. The G and B data is also significantly poorer. For the time being, pending any other confirmation, I would assume that it is a processing artefact.

Received: 12 December 2018 at 23:57 JST

 

Thanks for the image, Clyde.

 

When Arsia Mons is not itself visible and the cloud is centered over it, the feature is called Arsia Silva. This name was used by observers of 100 years ago. The sheet of clouds over Tharsis is a seasonal thing.

 

The view of O.M. is interesting in that it appears to show the relatively bright and dark sides of the mountain. This is not often seen so clearly.

 

As for the features above and below the SPC, you are correct in suspecting that they are artifacts. Any very bright feature may produce diffraction effects around its edges, and the suspicion of diffraction effects is heightened when there is a sequence of bright-dark-bright-dark areas alternating, and the distance between them is the same as the distances between the bright and dark limb arcs (which are caused by diffraction).

Received: 12 December 2018 at 16:25 JST

 

Hi all,

A rather interesting data set from yesterday evening, where I had some reasonable seeing conditions. In particular the G and B data was quite pleasing. The final images are from two sets of RGB data which have been derotated over a total period of +-8mins.

a. Quite extensive cloud is seen over Tharsis, with a bright concentration over Arsia Mons(B image). I am not sure if this is a remnant of the linear cloud that has been seen and monitored over the last few months.

b. Olympus Mons is seen at lower right in early morning conditions. Its dark western flank is seen close to the terminator.

c. However, what was of particular interest to me was the region around the SPC, where there is what appears to be a Blue/Green cloud possibly extending beyond the limb. This is enhanced/exacerbated by the fact that this limb area is dark in R. But the G and B data does appear to show it quite clearly. I have not seen anything like this in my recent images, and the fact that the B and G data is fairly good possibly adds some credence. However, pending further observations or confirmation, there is off course the possibility that it could be an artefact, given my current processing skills. Any comments would be welcome.

Best regards, Clyde

Dear all,

Two late images of Mars from Nov 25 and 26 as it is getting higher in the sky and now culminates at 24 degree altitude. These are my first Mars images since July and also with a new color camera. Great fun to see the albedo features are now back to normal contrast. Very little atmospheric activity though, the SPC is small and easily seen.

 

On the 26th, InSight landed just three hours after the image capture.

¤·····Subject: Mars 2 December 2018 1756UT RGB and IR. 13 inch Boyden Refractor

Received: 8 December 2018 at 23:20 JST

 

Hi all,

It was a privilege for me to be able to visit the Boyden Observatory in Bloemfontein on the weekend of the 2 December, and to image Mars through the historic 13h Alvan Clark refractor that dates back to 1887. This telescope has a special Mars heritage as William Pickering used it to photographically image the planet in 1888 when it was at Cambridge, Massachusetts, USA.

The greatest challenge was the manual focussing mechanism that had some play in it.

I have to thank Prof Matie Hoffman and Dawid van Jaarsfeld of UFS/Boyden Observatory and members of ASSA Bloemfontein for this opportunity and providing assistance.

 


 


 

The Boyden Observatory is closely linked with the Naval Hill planetarium which was originally the Lamont-Hussey Observatory where Earl Slipher made important Mars observations. I am pleased to say that the tube and mount of the original 27h refractor are being restored and will be mounted outside the entrance to the planetarium. The primary objective lens is at University of Michigan.

Best regards, Clyde

Received: 7 December 2018 at 16:34 JST

 

Dears,

We had a very successful pro-am session during the European Planetary Science Congress in Berlin mid of September, with a record number of presentations and posters covering greatly what we amateurs can do on the solar system studies.

You'll find here http://www.astrosurf.com/delcroix/doc/EPSC2018/EPSC2018.htm a page where presentations and posters are available (clicking on EPSC2016-XXX links), along with some pictures.

I am looking forward next congress in Geneva to have another exciting meeting with amateurs and professionals.

Regards,

Hi all,

Here is an image of Uranus from November 27th. Very good seeing. Not much to see aside from the bright polar region and faint equatorial band.
