¤·····Subject: Uranus 2018 - final results (spectro and photometry)

Received: 29 April 2019 at 22:33 JST

Hi all,
After months of work I'm sending more results on my Uranus'spectroscopic observation of last year. For this last data, my interest was to try to calibrate in intensity the spectrum of the planet. The idea is simply to experiment more ways of comparing data through the years.

Because a complete explanation of how I got those results would far exceed the capacity of an e-mail, I have re-opened my old Astrosurf website with some complete articles:

http://www.astrosurf.com/pellier/

1) The spectrum of Uranus in absolute flux

Explanation http://www.astrosurf.com/pellier/uranus_absolute-flux.html
I have "misused" the concept of absolute flux spectrum to process the Uranus spectrum. With some limits explained in the article, this was a rather easy result.

2) Calculating BVRI Johnson magnitudes

This has been complicated and asked for a great amount of work and observations. I'm using an experimental method of spectrophotometry. Please read:

http://www.astrosurf.com/pellier/photometry_fullspectrum.html
http://www.astrosurf.com/pellier/photometry_SAcolorcoeff.html
And the results:
http://www.astrosurf.com/pellier/uranus_photometry.html
The results may still lack accuracy but I'm currently on the learning curve. On the website you will find more experiences in photometry (on variable stars)

Despite the modest equipment I'm using, this is supposed to be a serious project so if you have any comment or critic, please send them to me.

Best wishes,

Christophe PELLIER (Nantes, FRANCE)

Hi All,

A Mars image from the other night....fair conditions for a short time.

As an experiment I went for a slightly longer focal length than usual.

Also I used an experimental way of processing these small discs so that any 'rind' on the bright edge is minimised,

hopefully preserving detail.

Hi,
A breeze from the East and cold skies (radiative temp of -26C) was not expected to yield anything decent- but it's always worth trying. Mars at 4.5" in RGB and IR and just over 30° alt.

Dears,

The professional astronomy conference European Planetary Science Congress/Division for Planetary Science joint meeting 2019 (EPSC-DPS 2019) will be held from September 15 to September 20, 2019 in Geneva, Switzerland. This yearly European conference, this year common with its American equivalent,, gives an inspiring insight of the latest discoveries and the current status of Solar System astronomy and planetary science and wellcomes the participation of amateur astronomers.

In particular the AM1 session "Professional-amateur collaborations in small bodies, terrestrial and giant planets, exoplanets, and fround-based support for space missions" is organized by amateur astronomers together with professionals and are open to presentations by amateurs. We invite you to actively participate to these sessions by contributing a paper (fill in the abstract submission form in the "Outreach, Diversity, Amateur Astronomy" program group, deadline May 8th, 2019. You can also attend to this sesion exchange views and ideas with other amateur and professional astronomers. Contributions will be oral talks and poster contributions. The language at the meeting will be English for all presentations.

There could be some funding available at least for early career researcher and underrepresented country, more details will be available on the website in the next weeks.

Please feel free to circulate this message to all those who might be interested in the event.

Dears,

After several months with hardly any observing, it was good to be back outside, I was motivated enough to image despite the bad seeing.

Only images in infrared, as it was already dawn when I started:
