INDEX BENJAMIN APTHORP GOULD BENJAMIN APTHORP GOULD, JR. 1814 August 24, Wednesday: Viscount Castlereagh arrived at Paris, where he would be meeting with King Louis XVIII and Talleyrand before traveling on to Vienna. As part of a conflict that was essentially a continuation of the American Revolution by way of a dispute over the seas and over the border of Canada, on this day and the following one a British army defeated hastily assembled defenders of Washington DC at Bladensburg, Maryland, just north of the capital. The British would go on to burn Washington, including the White House and most of the 3,076 books and 53 maps, charts, and plans of the Library of Congress, along with paintings of Louis XVI and Marie Antoinette by Madame Vigee Lebruin. They would also put the chambers of the House and the Senate in Washington DC to the torch — but beware, it is sheer mythology that the books were used as kindling for the fire in the legislative chambers.1 Waldo Emerson would reminisce in his journal in about April or May of 1856 about a British-invasion-of- Boston scare that had occurred in about this period of his childhood:2 I have but one military recollection in all my life. -

The Newsletter of Westchester Amateur Astronomers December 2019 M8-The Lagoon Nebula by Gary Miller A familiar object at summer star parties, M8 in Sagittarius was first glimpsed by John Flamsteed in 1680 and called “The Lagoon Nebula” by the Irish astronomer Agnes Clerke in The System of the Stars (1890). It is an emission nebula which re-radiates the energy of several hot young stars embedded within it, including 9 Sagittari (dead center). It also surrounds the open cluster NGC 6530, a system of 113 young stars. Although it’s low in the summer sky from Westchester, it’s a wonderful visual object in nearly any telescope.

T Vulpeculae
T Vulpeculae: Maximum Times covering 120 years show a slight, continuous Period Decrease US astronomer Benjamin Apthorp Gould (1824...1896) studied in Germany, namely mathematics in Göttingen from Prof. Gauss and astronomy in Bonn from Prof. Argelander. Back home Gould started a visual sky survey to complete Argelander's Bonner Durchmusterung. After Gould had departed to observe in Argentina his assistant Seth Carlo Chandler jr. (1846...1913) in 1876 recruited the Boston bank clerk Edwin F. Sawyer to contribute with own visual observations. It seems, that Sawyer observed at least until about 1900. During these 25 years with the visual comparison methods of his time Sawyer discovered a remarkable number of variable stars, among them (Sawyer, 1885) the bright, classical cepheid T Vulpeculae. T Vul is about the 10th in apparent magnitude of all classical cepheids. A modern database (DDODB, ca. 1996) reports a mean magnitude of 5,75mag and an amplitude of 0,64mag. The period is 4,4 days. The lightcurve (figure 1) produces the typical smooth, asymmetric pattern of classical cepheids with periods between 3 and 6 days. Around 1900 the term "cepheid" had not yet been introduced. Researchers designated variables with asymmetric lightcurves and periods shorter than 50 days as short period variables. Karl Schwarzschild (1900) discovered, that brightness and brightness variation of a star on photographic plates can be much different from visual ones. In the following years scientists recognized, that short period variables show this phenomenon to an especially marked amount. Authors of the 1920ies and 1930ies continued to study this by comparing visual magnitudes or magnitudes on panchromatic, sensitised ("photovisual") plates on one with magnitudes on unsensitised, blue sensitive ("photographic") plates on the other side. -

One night, in June 1782, the Astronomer Royal Nevil Maskelyne suddenly felt “much out of love with his instrument.”1 William Herschel had come to Greenwich to stargaze in his company and Maskelyne had welcomed him. But to realize that all telescopes in the Royal Observatory were so much inferior to Herschel’s new reflector was disheartening to the Astronomer Royal. -

There are ap proximately 600,000 plates at the Harvard College Observatory, 20,000 at the Bologna Uni versity Observatory, 80,000 at the Odessa Astronomical Observatory, to give just a few examples (Hudec 1999). The designation of these collections as “archives” is mostly ret rospective, but the glass plate pictured here was destined from the outset to be part of an archive: the vast astrophotographic survey of the sky as seen from the earth known as the Carte du Ciel. -
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. -
Biographical Memoir of Asaph Hall*
BIOGRAPHICAL MEMOIR ASAPH HALL 1829-1907 GEORGE WILLIAM HILL READ HEI-OIIK THE NATION.\I, ACADEMY OF SCIENCES AI-KH> 2:>, loos (25) 241 BIOGRAPHICAL MEMOIR OF ASAPH HALL* Tn commencing the story of a remarkable man of science, it is necessary to say something of his lineage, in spite of the gener- ally held opinion that the details of genealogy make dry read- ing, f ASAPH HALL undoubtedly descended from John Hall, called of New Haven and Wallingford to distinguish him from the other numerous John Halls of early New England (Savage makes no less than seven before 1660), and who arrived at New Haven shortly after June 4, 1639, as he is one of the after-signers of tlie New Haven Planters' Covenant. His movements before his arrival are in some obscurity. From his son Thomas of Wal- lingford receiving a grant of fifty acres of land from the General Court of the Colony at the session of October, 1698, "In consid- eration of his father's services in the Pequot war," it is inferred that he was a dweller in the colony in 1637. At this date there were only four settlements in Connecticut, and it is supposed that the John Hall of New Haven is identical with a John Hall who appears as the holder of lots in Hartford about 1635. The genealogists arc in dispute in the matter. Mr. Shepard sums up thus: John Hall came with the advance Hooker party, in 1632, or perhaps on the Griffin or the Bird (two vessels whose arrival at Massachusetts Bay is mentioned by Winthrop), September 4, 1633. -

NATIONAL ACADEMY OF SCIENCES Ch RISTIAN HEINRIC H F RIEDRIC H PETERS A Biographical Memoir by W I L L I A M ShEE H AN Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1999 NATIONAL ACADEMIES PRESS WASHINGTON D.C. CHRISTIAN HEINRICH FRIEDRICH PETERS September 19, 1813–July 18, 1890 BY WILLIAM SHEEHAN N THE MID-NINETEENTH century the discovery of new aster- Ioids was still far from routine. These objects had not yet grown so numerous as to earn for themselves the contemp- tuous label later applied, “vermin of the skies,” and those who excelled in claiming the starlike wanderers from the camouflage of background stars were honored with renown. Hind, de Gasparis, Goldschmidt, Chacornac, Pogson, and Peters were foremost among the early discoverers. Even on this short list C. H. F. Peters stood out. On May 29, 1861—just weeks after the American Civil War began at Fort Sumter—Peters discovered his first aster- oid (72 Feronia). It was the fifth asteroid discovered in North America (others had been found by Ferguson and Searle). Feronia was the first of forty-eight such discoveries that made Peters the most prolific finder of minor planets of his generation, and even today he remains second only to Johann Palisa among visual discoverers of asteroids. Dur- ing his colorful career, he also compiled meticulous star charts of the zodiac, collated observations from manuscripts of Ptolemy, and embroiled himself in a series of often bitter controversies with other astronomers, notably over the ex- istence of an intra-Mercurial planet.
