They haven't been updated with slick, busy activities in San Diego. An undoubted highlight was a Sunday visit graphics, but just with more information. Visit our web site at to the Ernst Zinner Collection of historic astronomical books and http:l/www.aas.org/%7Ehad/had.html documents at San Diego State University, hosted by Freddie Talbert and you will find the updated list of HAD officers and links to lists of the astronomy faculty and Lyn Olsson of the SDSU Library's of former officers and the sites and dates of past HAD meetings.

Doggett Prize for I-Iistorical Astronomy. And perhaps the collection constitutes his personal library. Emphasizing most exciting addition is Ruth Freitag's bibliography of recent astronomy, but including horology and the history of science, the publications in the history of astronomy. Right now her collection consists of more than thirty-five hundred books and is bibliography for the Feb. 2001 HAD News is up in both HTML and rich in rare books dating from 1485. Our hosts peppered the SDSU PDF formats. We hope to add earlier bibliographies as we get a campus with many signs pointing the way to the new library annex chance. where the Special Collections reside on the top floor (a few of us still got lost, however). As well as displaying classic works by Galileo, Copernicus, and many others, Lyn provided some guidance in how such volumes should be handled-not necessarily with gloves, which are likely to tear fragile pages-with very clean, oil-free, delicate human fingers. None of us dared try, but we bent closely over, making remarks like "that lion must have been drawn by someone who had never seen a lion," and "that's not a scorpion, that's a tick," in response to John Flamsteed's Atlas Coelestis of 1753 (no, it doesn't show Cas A). Another highlight was their latest, late December, acquisition, Johannes Kepler's Rndolp!iine Tables of 1627, with a world map added some time later. After a brief visit to the Special Collections department, the first HAD session took place down the lull in the conference room. The theme of the Sunday session was "Boners of the Century." The first talk was by A.T, Young (SDSU) on "J. B. Biot and Refraction Calculations." Young pointed out that Biot had approached atmospheric refraction from an incorrect theory of light, but nevertheless obtained more nearly correct results than many later practitioners, the results having been forgotten to our detriment. (continued on page 2) Lyn Olsson (SDSU Special Collections) gives HAD members a close encounter of the third ( 1726) edition of Newton's Principia (photo by David DeVorkin) HAD in San Diego (continued from page 1) sources. B. McNamara (NMSU), in "The Mercury 13 and the Selection of Women Astronauts," brought us closest to the present, We also learned that Biotite Mica is named for the multi-talented looking at the baker's dozen American women initially selected for Biot!

B.E. however, the final joint AAPT-AAS session speaker addressed a Schaefer (UT-Austin), in "The Transit of Venus and the Notorious historical topic. Dennis Danielson, Professor of English at the Black Drop," drew attention to the several wrong explanations of University of British Columbia, spoke on "The Great Copernican the black drop effect (when Venus-or Mercury-transits the sun) Cliche." His thesis was that most astronomers, and a good many that are more often found in textbooks than is the correct, image- historians, badly misunderstand the change from geocentric to smearing and isophote-tracing, answer.

  • Observation of Venus and Mercury Transits from the Pic-Du-Midi Observatory
    MEETING VENUS C. Sterken, P. P. Aspaas (Eds.) The Journal of Astronomical Data 19, 1, 2013 Observation of Venus and Mercury Transits from the Pic-du-Midi Observatory Guy Ratier 43 rue des Longues All´ees, F-45800 Saint-Jean-de-Braye, France Sylvain Rondi Soci´et´eAstronomique de France, 3 rue Beethoven, F-75016 Paris France Abstract. The Pic-du-Midi, on the French side of the Pyr´en´ees, became a state observatory in the summer of 1882. The first major astronomical event to be observed was the Venus transit of 6 December 1882. Unfortunately this attempt by the well-known Henry brothers was unsuccessful due to bad weather conditions. During the twentieth century, the Pic-du-Midi became famous for the quality of its solar and planetary observations. In the sixties, Jean R¨osch decided to use this experience to monitor the transits of Mercury. The objective was not to measure the parallax, but to determine the diameter of the planet in order to confirm its high density. Observations were made using a photometric method – the Hertzsprung method – during the transits of 1960, 1970 and 1973. The pioneer work of Ch. Boyer on the rotation of the Venus atmosphere as well as some experiments involving Lyot coronographs are also noteworthy. A Venus transit was finally observed on 8 June 2004 with a new CCD camera, providing a significant contribution to the model of the Venus mesosphere. This opened the field for new observations in 2012. 1. Early days of the Pic-du-Midi Observatory The site of the “Pic-du-Midi de Bigorre”, on the forefront of the Pyr´en´ees, has been known since ages as an ideal location to carry out astronomical observations.

  • Year of the Dwarves: Ceres and Pluto Take the Stage
    Year of the Dwarves: Ceres and Pluto Take the Stage — Paul Schenk, Lunar and Planetary Institute The year 2015 is shaping up to be one of the most interesting in the short history of space exploration. Fresh on the heels of Rosetta’s spectacular and revolutionary ongoing visit to a comet, and after a wait of more than half a century, we finally reach the first of the so-called dwarf planets, the last class of solar system bodies left unexplored. This year the Dawn and New Horizons missions will both reach their primary targets, Ceres and Pluto. Indeed, Dawn is on its final approach to Ceres as this is being written. Both Ceres and Pluto are very planetary in nature. Each is the major representative of its planetary zone. LCeres holds about one-third of the total mass in the asteroid belt, and may be actively venting water vapor into space. Pluto is likely the largest Kuiper belt object (KBO), and even has a significant atmosphere and a family of at least five moons. What will we see at Ceres and Pluto? Scientists and interested laypeople have been speculating quite a lot as we approach these two bodies. In some sense, it is an opportunity to test how well we really understand planetary bodies. Both Ceres P and Pluto (and its large moon Charon) are believed to be rich in water ice. Pluto is known to have other ices on its surface, include methane, nitrogen, and carbon monoxide. We are fortunate that we have already extensively mapped comparably- Our best Earth-based views of Ceres (left) and Pluto (right), sized ice-rich bodies, which serve as both from Hubble Space Telescope images.

We carry out a solar survey with images of the photosphere, prominences, and corona at Pic du Midi observatory. This sur- vey, named CLIMSO (for CLIchés Multiples du SOleil), is in the following spectral lines: Fe XIII corona (1.075 µm), Hα (656.3 nm), and He I (1.083 µm) prominences, and Hα and Ca II (393.4 nm) photosphere. All frames cover 1.3 times the diameter of the Sun with an angular resolution approaching one arcsecond. The frame rate is one per minute per channel (weather permitting) for the prominences and chromosphere, and one per hour for the Fe XIII corona. This survey started in 2007 for the disk and prominences and in 2015 for the corona. We have almost completed one solar cycle and hope to cover several more, keeping the same wavelengths or adding others. Aims. We seek to make the CLIMSO images easier to use and more profitable for the scientific community.

  • Reviews the History of Astronomy
    Reviews The history of astronomy by Heather Couper & Nigel Henbest Cassell Illustrated, 2007. ISBN 978- 1-84403-570-0. Pp 288 (247× 297mm), £30 (hbk). One of the great joys of the history of astronomy is that it can be treated on many different levels. You can delve deep and immerse yourself in four hundred page tomes on the significance of the ob- servations of the comet of 1577, and you can wallow in a huge three volume set of the letters of John Flamsteed, our first Astronomer Royal, or you can flit briefly and joyfully from highlight to highlight. Heather Couper and Nigel Henbest adopt the latter approach. They have travelled widely and interviewed many of the key players in recent astronomical and astrophysical history, as well as those who study the development of as- tronomy over the past few thousand years. The views of the authors and the peo- ing at some of the pictures of famous astro- ple they interviewed have then been skil- nomical scientists, one can often pick up fully knitted together to produce an im- hints of the darker side.

  • 107 V Ariations on the Unexpected
    107 Variations on the Unexpected SURPRISE 107 Variations on the Unexpected Dedication and Prelude To Raine Daston In his essay “Of Travel,” Francis Bacon recommends that diaries be used to register the things “to be seen and observed.” Upon returning home, the traveler should not entirely leave the visited countries, but maintain a correspondence with those she met, and let her experi- ence appear in discourse rather than in “apparel or gesture.” Your itineraries through a vast expanse of the globe of knowledge seem to illustrate Bacon’s recommendations, and have inspired many to em- bark on the exploration of other regions—some adjacent, some dis- tant from the ones you began to clear. Yet not all have journeyed as well equipped as you with notebooks, nor assembled them into a trove apt to become, as Bacon put it, “a good key” to inquiry. As you begin new travels, you may add the present collection to yours, and adopt the individual booklets as amicable companions on the plane or the U-Bahn. Upon wishing you, on behalf of all its contributors, Gute Reise! and Bon voyage!, let us tell you something about its gen- esis and intention. Science depends on the unexpected. Yet surprise and its role in the process of scientific knowledge-making has hitherto received lit- tle attention, let alone systematic investigation. If such a study ex- isted, it would no doubt have been produced in your Department at the Max Planck Institute for the History of Science. The topic is a seamless match with your interest in examining ideals and practices of scientific and cultural rationality—ideals and practices often so fundamental that they appear to transcend history or are overlooked altogether.

  • The Pre-Embryonic State of the AAVSO
    154 Saladyga, JAAVSO Volume 27, 1999 THE “PRE-EMBRYONIC” STATE OF THE AAVSO: AMATEUR OBSERVERS OF VARIABLE STARS IN THE UNITED STATES FROM 1875 TO 1911 Michael Saladyga AAVSO Headquarters 25 Birch Street Cambridge, MA 02138 Presented at the 87th Annual Meeting of the AAVSO, October 31, 1998 Abstract For 35 years before the formation of the AAVSO, independent amateur variable star astronomers in the United States were making significant contributions to the field. Skilled, dedicated individuals like S. C. Chandler, E. F. Sawyer, and P. S. Yendell laid the foundation in variable star work that was expanded upon by Harvard College Observatory Director E. C. Pickering, under whose direction a new generation of enthusiastic amateur and professional astronomers continued to further the cause of variable star research. This paper is a survey of the contributions made by several independent amateur variable star astronomers, and it is also a chronology of the growth of a broader, more popularized, amateur involvement in variable star astronomy which led to the organization of the AAVSO in 1911. 1. Introduction The German astronomer Friedrich Argelander is well-known in variable star histories as the “father of variable star observing.” The professional astronomer Argelander in 1844 first brought to the attention of the astronomical community the phenomena of variable stars and the need for observations of them. His Uranometria Nova catalogue of the magnitudes of over 3,500 northern stars was a great boost to the involvement of amateur observers of variable stars in Europe. This catalogue was not widely available in America, hence the late start here in amateur variable star work.
