The Astronomers Tycho Brahe and Johannes Kepler
Ice Core Records – From Volcanoes to Supernovas The Astronomers Tycho Brahe and Johannes Kepler Tycho Brahe (1546-1601, shown at left) was a nobleman from Denmark who made astronomy his life's work because he was so impressed when, as a boy, he saw an eclipse of the Sun take place at exactly the time it was predicted. Tycho's life's work in astronomy consisted of measuring the positions of the stars, planets, Moon, and Sun, every night and day possible, and carefully recording these measurements, year after year. Johannes Kepler (1571-1630, below right) came from a poor German family. He did not have it easy growing Tycho Brahe up. His father was a soldier, who was killed in a war, and his mother (who was once accused of witchcraft) did not treat him well. Kepler was taken out of school when he was a boy so that he could make money for the family by working as a waiter in an inn. As a young man Kepler studied theology and science, and discovered that he liked science better. He became an accomplished mathematician and a persistent and determined calculator. He was driven to find an explanation for order in the universe. He was convinced that the order of the planets and their movement through the sky could be explained through mathematical calculation and careful thinking. Johannes Kepler Tycho wanted to study science so that he could learn how to predict eclipses. He studied mathematics and astronomy in Germany. Then, in 1571, when he was 25, Tycho built his own observatory on an island (the King of Denmark gave him the island and some additional money just for that purpose). -

A Needs Analysis Study of Amateur Astronomers for the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2
A Needs Analysis Study of Amateur Astronomers For the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2 1Clinton B. Ford Astronomical Data & Research Center American Association of Variable Star Observers 25 Birch St, Cambridge MA 02138 2Space Sciences Laboratory University of California, Berkeley 7 Gauss Way Berkeley, CA 94720-7450 Abstract Through a combination of qualitative and quantitative processes, a survey was con- ducted of the amateur astronomy community to identify outstanding needs which the National Virtual Observatory (NVO) could fulfill. This is the final report of that project, which was conducted by The American Association of Variable Star Observers (AAVSO) on behalf of the SEGway Project at the Center for Science Educations @ Space Sci- ences Laboratory, UC Berkeley. Background The American Association of Variable Star Observers (AAVSO) has worked on behalf of the SEGway Project at the Center for Science Educations @ Space Sciences Labo- ratory, UC Berkeley, to conduct a needs analysis study of the amateur astronomy com- munity. The goal of the study is to identify outstanding needs in the amateur community which the National Virtual Observatory (NVO) project can fulfill. The AAVSO is a non-profit, independent organization dedicated to the study of vari- able stars. It was founded in 1911 and currently has a database of over 11 million vari- able star observations, the vast majority of which were made by amateur astronomers. The AAVSO has a rich history and extensive experience working with amateur astrono- mers and specifically in fostering amateur-professional collaboration. AAVSO Director Dr. Janet Mattei headed the team assembled by the AAVSO. -

A wide-field imaging study with interference filters has revealed 35 new Herbig-Haro objects in the Gulf of Mexico. A grism survey has identified 41 Hα emission- line stars, 30 of them new. A small cluster of partly embedded pre-main sequence stars is located around the known LkHα 185-189 group of stars, which includes the recently erupting FUor HBC 722. Key words. Herbig-Haro objects – stars: formation 1. Introduction In a grism survey of the W80 region, Herbig (1958) detected a population of Hα emission-line stars, LkHα 131–195, mostly The North America nebula (NGC 7000) and the adjacent Pelican T Tauri stars, including the little group LkHα 185 to 189 located nebula (IC 5070), both well known for the characteristic shapes within the dark lane of the Gulf of Mexico, thus demonstrating that have given rise to their names, are part of the single large that low-mass star formation has recently taken place here. -

Monitoring Solar Activity Trends with a Simple Sunspotter
Larsen, JAAVSO Volume 41, 2013 373 Monitoring Solar Activity Trends With a Simple Sunspotter Kristine Larsen Physics and Earth Sciences, Central Connecticut State University, 1615 Stanley Street, New Britain, CT 06053; [email protected] Presented at the 101st Annual Meeting of the AAVSO, November 11, 2012; received May 7, 2013; revised November 12, 2013; accepted November 13, 2013 Abstract With the Sun now in solar maximum, solar observations are a timely means to interest students and the general public in astronomy in general and variable stars in particular. The commercially produced Sunspotter is a solar projection system that allows for safer solar observations by several individuals simultaneously. Educational uses for the Sunspotter are reviewed, and the ability of the instrument to track trends in the sunspot cycle (compared to a standard telescope and the American Relative Sunspot Number (Ra)) is examined. 1. Introduction One of the areas where students and amateur astronomers have provided a valuable service to the discipline is in the field of solar observing. For example, Elizabeth Brown led the Solar Section of the Liverpool Astronomical Society in the 1880s, and then the British Astronomical Association in the 1890s. She aggregated the sunspot counts and drawings of other amateurs for use by the Greenwich Royal Observatory and other scientists interested in the growing field of solar astronomy (Brück 2009). In the United States, Vassar College astronomy professor Maria Mitchell set her students to work at first observing and then photographing the Sun as early as 1874 (Mitchell 1890). These observations were published in Scientific American nearly monthly between January 1875 and January 1881. -
