I’ll save that sharing their hobby with the public. retrospection for next month’s issue of The OBSERVER, but I’ve already begun.

Hardly a week goes by when Diann hasn’t Carl J. Wenning 309-830-4085 mentioned to someone that I’m “into” astronomy. She shows them some of my [email protected] images, and delights in their wide-eyed “he took THAT?” response. She regales me Director/Technology Coordinator with those stories, and it lets me know that she’s okay with the inconveniences she Justin Meyer 630-649-0611 experiences on those long clear nights.

Perhaps they don’t even Webmaster Lee Green 309-454-7349 recognize how much it means to us. Let them know, and please accept my own [email protected] thanks to you, the amateur astronomy community and the TCAA, for whatever way you are involved.

  • The Astronomical Garden of Venus and Mars-NG915: the Pivotal Role Of
    The astronomical garden of Venus and Mars - NG915 : the pivotal role of Astronomy in dating and deciphering Botticelli’s masterpiece Mariateresa Crosta Istituto Nazionale di Astrofisica (INAF- OATo), Via Osservatorio 20, Pino Torinese -10025, TO, Italy e-mail: [email protected] Abstract This essay demonstrates the key role of Astronomy in the Botticelli Venus and Mars-NG915 painting, to date only very partially understood. Worthwhile coin- cidences among the principles of the Ficinian philosophy, the historical characters involved and the compositional elements of the painting, show how the astronomi- cal knowledge of that time strongly influenced this masterpiece. First, Astronomy provides its precise dating since the artist used the astronomical ephemerides of his time, albeit preserving a mythological meaning, and a clue for Botticelli’s signature. Second, it allows the correlation among Botticelli’s creative intention, the historical facts and the astronomical phenomena such as the heliacal rising of the planet Venus in conjunction with the Aquarius constellation dating back to the earliest represen- tations of Venus in Mesopotamian culture. This work not only bears a significant value for the history of science and art, but, in the current era of three-dimensional mapping of billion stars about to be delivered by Gaia, states the role of astro- nomical heritage in Western culture. Finally, following the same method, a precise astronomical dating for the famous Primavera painting is suggested. Keywords: History of Astronomy, Science and Philosophy, Renaissance Art, Educa- tion. Introduction Since its acquisition by London’s National Gallery on June 1874, the painting Venus and Mars by Botticelli, cataloged as NG915, has remained a mystery to be interpreted [1]1.

We had a good time, and About 100 people (adult and children) attended. Ben Toman live streamed on the BRAS Facebook page. See his description in this newsletter. A copy of the proposed, revised By-Laws should be in your mail soon. Read through them, and any proposed changes need to be communicated to me before the November meeting. Wally Pursell (who wrote the original and changed by-laws) and I worked last year on getting the By-Laws updated to the current BRAS policies, and we hope the revised By-Laws will need no revisions for a long time. We need more Globe at Night observations – we are behind in the observations compared to last year at this time. We also need observations of variable stars to help in a school project by a new BRAS member, Shreya.

    September 2016 Issue th Next Meeting: Monday, Sept. 12 at 7PM at HRPO (2nd Mondays, Highland Road Park Observatory) What's In This Issue? Due to the 1000 Year Flood in Louisiana beginning August 14, some of our club’s activities were curtailed, thus our newsletter is shorter than usual. President’s Message Secretary's Summary for August (no meeting) Light Pollution Committee Report Outreach Report Photo Gallery 20/20 Vision Campaign Messages from the HRPO Triple Conjunction with Moon Observing Notes: Capricornus – The Sea Goat, by John Nagle & Mythology Newsletter of the Baton Rouge Astronomical Society September 2016 BRAS President’s Message This has been a month of many changes for all of us. Some have lost almost everything in the flood, Some have lost a little, and some have lost nothing... Our hearts go out to all who have lost, and thanks to all who have reached out to help others. Due to the flooding, last month’s meeting, at LIGO, was cancelled. The September meeting will be on the 12th at the Observatory, which did not receive any water during the flood, thus BRAS suffered no loss of property. As part of our Outreach effort. If anyone you know has any telescope and/or equipment that was in water during the flood, let us know and we will try to help clean, adjust, etc. the equipment. On September 2nd (I am a little late with this message), Dr. Alan Stern, the New Horizons Primary Investigator, gave two talks at LSU. The morning talk was for Astronomy graduate students, and was a little technical.

Received: 5 May 2014; in revised form: 20 June 2014 / Accepted: 16 July 2014 / Published: 7 August 2014 Abstract: The significance of Stark broadening data for problems in astrophysics, physics, as well as for technological plasmas is discussed and applications of Stark broadening parameters calculated using a semiclassical perturbation method are analyzed. Keywords: Stark broadening; isolated lines; impact approximation 1. Introduction Stark broadening parameters of neutral atom and ion lines are of interest for a number of problems in astrophysical, laboratory, laser produced, fusion or technological plasma investigations. Especially the development of space astronomy has enabled the collection of a huge amount of spectroscopic data of all kinds of celestial objects within various spectral ranges. Consequently, the atomic data for trace elements, which had not been
