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.

  • Extrasolar Planets and Their Host Stars
    Kaspar von Braun & Tabetha S. Boyajian Extrasolar Planets and Their Host Stars July 25, 2017 arXiv:1707.07405v1 [astro-ph.EP] 24 Jul 2017 Springer Preface In astronomy or indeed any collaborative environment, it pays to figure out with whom one can work well. From existing projects or simply conversations, research ideas appear, are developed, take shape, sometimes take a detour into some un- expected directions, often need to be refocused, are sometimes divided up and/or distributed among collaborators, and are (hopefully) published. After a number of these cycles repeat, something bigger may be born, all of which one then tries to simultaneously fit into one’s head for what feels like a challenging amount of time. That was certainly the case a long time ago when writing a PhD dissertation. Since then, there have been postdoctoral fellowships and appointments, permanent and adjunct positions, and former, current, and future collaborators. And yet, con- versations spawn research ideas, which take many different turns and may divide up into a multitude of approaches or related or perhaps unrelated subjects. Again, one had better figure out with whom one likes to work. And again, in the process of writing this Brief, one needs create something bigger by focusing the relevant pieces of work into one (hopefully) coherent manuscript. It is an honor, a privi- lege, an amazing experience, and simply a lot of fun to be and have been working with all the people who have had an influence on our work and thereby on this book. To quote the late and great Jim Croce: ”If you dig it, do it.

  • Les Etoiles Fixes Entretien Avec Diana K. Rosenberg
    Les Etoiles Fixes Entretien avec Diana K. Rosenberg Edith Hathaway, USA. © 2010 http://edithhathaway.com/pdf/DianaKRosenbergInterview.pdf Traduction Française : Patricia Depasse, Belgique © 2015 Robert Hand dit que Diana K. Rosenberg est “LA référence en Etoiles Fixes’’. Elle a passé 30 ans de sa vie à investiguer le sujet. Elle s’est toujours intéressée à la recherche et à l’enseignement, plutôt qu’à la consultation. Ses techniques astrologiques favorites, en dehors du domaine des Etoiles Fixes, comprennent l’astrologie uranienne (carte de 90 degrés, figures planétaires etc.), les maisons dérivées, les nœuds planétaires et les points solsticiaux. Diana a résidé à New York City tout au long de sa vie, alors que je n’y ai passé que 7 ans, pour me diriger vers l’ouest des USA en février 1983. Nos chemins se sont croisés pour la première fois en 1982, alors que je suivais les cours de Diana en astrologie uranienne, à Manhattan. De 1988 au début des années 1990, je me suis portée graduellement de l’astrologie uranienne (tropicale) à l’astrologie védique (sidérale), un sujet que Diana avait toujours prévu d’étudier, mais les Etoiles Fixes lui ont pris tout son temps. Elle a toujours été fascinée par les choses très anciennes, et par l’étude de l’Antiquité. Une autre partie de cette interview, surtout sur les Etoiles Fixes, est publiée aussi par le ISAR Journal (Journal of the International Society for Astrological Research), version imprimée et en ligne. Cf. http://www.isarastrology.com. Cette plus longue interview chez Saptarishis ne couvre que quelques pages sur le même sujet, mais bien davantage sur Diana et sur les Etoiles Fixes.
