Collana diretta da Rosalma Salina Borello e Luca Nicotra Prima edizione: maggio 2010 Universitalia INTRODUZIONE Introduzione Costantino Sigismondi L’edizione del convegno gerbertiano del 2009, in pieno anno internazionale dell’astronomia, si è tenuta nella Basilica di S. Maria degli Angeli e dei Martiri il 12 maggio, e a Seoul presso l’università Sejong l’11 giugno 2009. La scelta della Basilica è dovuta alla presenza della grande meridiana voluta dal papa Clemente XI Albani nel 1700, che ancora funziona e consente di fare misure di valore astrometrico. Il titolo di questi atti, ORBE NOVUS, è preso, come i precedenti, dall’epitaffio tombale di Silvestro II in Laterano, e vuole suggerire il legame con il “De Revolutionibus Orbium Coelestium” di Copernico, sebbene il contesto in cui queste parole sono tratte vuole inquadrare Gerberto nel suo ministero petrino come il nuovo pastore per tutto il mondo: UT FIERET PASTOR TOTO ORBE NOVVS. Elizabeth Cavicchi del Massachussets Institute of Technology, ha riflettuto sulle esperienze di ottica geometrica fatte da Gerberto con i tubi, nel contesto contemporaneo dello sviluppo dell’ottica nel mondo arabo con cui Gerberto era stato in contatto.

One object or body provides a distance but the observer can be anywhere on a circle of that radius away from the object. At least two distances/ circles are necessary for a position. (Three avoids ambiguity.) In practice, only that part of the circle near an assumed position would be drawn. Using a Sextant for Celestial Navigation After a few corrections, a sextant gives the true distance of a body if measured on an imaginary sphere surrounding the earth. Using a Nautical Almanac to find the position of the body, the body’s position could be plotted on an appropriate chart and then a circle of the correct radius drawn around it. In practice the circles are usually thousands of miles in radius therefore distances are calculated and compared with an estimate.

Robles Macías* The longitude of the Mediterranean throughout history: facts, myths and surprises Keywords: History of longitude; cartographic errors; comparative studies of maps; tables of geographical coordinates; old maps of the Mediterranean Summary: Our survey of pre-1750 cartographic works reveals a rich and complex evolution of the longitude of the Mediterranean (LongMed). While confirming several previously docu- mented trends − e.g. the adoption of erroneous Ptolemaic longitudes by 15th and 16th-century European cartographers, or the striking accuracy of Arabic-language tables of coordinates−, we have observed accurate LongMed values largely unnoticed by historians in 16th-century maps and noted that widely diverging LongMed values coexisted up to 1750, sometimes even within the works of one same author.

The major ones are: maritime circular radiobeacons (RC), Decca-Navigator System (DNS) and Differential GPS (DGPS), as well as solutions forgotten today: AD-2 and SYLEDIS. In this paper, due to its limited volume, the authors have omitted the description of the solutions used by the Polish Navy (RYM, BRAS, JEMIOŁUSZKA, TSIKADA) and the global or continental systems (TRANSIT, GPS, GLONASS, OMEGA, EGNOS, LORAN, CONSOL) - described widely in world literature.

  • Stellarium for Cultural Astronomy Research
    RESEARCH The Simulated Sky: Stellarium for Cultural Astronomy Research Georg Zotti Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology, Vienna, Austria [email protected] Susanne M. Hoffmann Friedrich-Schiller-Universität Jena, Michael-Stifel-Center/ Institut für Informatik and Physikalisch- Astronomische Fakultät, Jena, Germany [email protected] Alexander Wolf Altai State Pedagogical University, Barnaul, Russia [email protected] Fabien Chéreau Stellarium Labs, Toulouse, France [email protected] Guillaume Chéreau Noctua Software, Hong Kong [email protected] Abstract: For centuries, the rich nocturnal environment of the starry sky could be modelled only by analogue tools such as paper planispheres, atlases, globes and numerical tables. The immer- sive sky simulator of the twentieth century, the optomechanical planetarium, provided new ways for representing and teaching about the sky, but the high construction and running costs meant that they have not become common. However, in recent decades, “desktop planetarium programs” running on personal computers have gained wide attention. Modern incarnations are immensely versatile tools, mostly targeted towards the community of amateur astronomers and for knowledge transfer in transdisciplinary research. Cultural astronomers also value the possibili- ties they give of simulating the skies of past times or other cultures. With this paper, we provide JSA 6.2 (2020) 221–258 ISSN (print) 2055-348X https://doi.org/10.1558/jsa.17822 ISSN (online) 2055-3498 222 Georg Zotti et al. an extended presentation of the open-source project Stellarium, which in the last few years has been enriched with capabilities for cultural astronomy research not found in similar, commercial alternatives.

  • ASTR 101L Astronomical Motions I: the Night Sky (Spring)
    ASTR 101L Astronomical Motions I: The Night Sky (Spring) Early Greek observers viewed the sky as a transparent sphere which surrounded the Earth. They divided the stars into six categories of brightness and arranged the stars into groupings called constellations (as did many other cultures). Most of the names of the eighty-eight constellations we use today are based on Greek mythology and their Latin translations. Modern astronomy uses the constellation designations to map the sky. On skymaps, the size of the dot is usually related to the brightness of the object (look on your planisphere). Most only show the brightest stars. They are typically named from brightest to faintest using a letter from the Greek alphabet (α, β, γ, etc.) and the constellation name in the genitive form; e.g. alpha (α) Cygni is the brightest star in Cygnus. Many stars also have Arabic names such as Betelgeuse, Algol, and Arcturus; α Cygni is named Deneb and α Ursa Minoris is more commonly known as Polaris. Either designation is correct. In the exercise “Angles and Parallax,” you made a cross-staff and quadrant and learned how to use them to measure objects inside. Now we will use them to measure objects in the night sky, much like Tycho Brahe did in the 1500’s. Remember to record the date, time, and conditions when making any astronomical observations! All numerical data should be recorded to one decimal place. Objectives: . Measure angular separations and altitudes of objects in the night sky with instruments . Estimate angular separations and altitudes of objects in the night sky with your hands .

  • Build Your Own Planisphere
    Make your own planisphere Dominic Ford 2014{2021 A planisphere is a simple hand-held device which shows a map of which stars are visible in the night sky at any particular time. By rotating a wheel, it shows how stars move across the sky through the night, and how different constellations are visible at different times of year. Here, I present a kit which you can download and print to make your own planisphere out of paper or cardboard. The design of a planisphere depends on the geographic location where it is to be used, since different stars are visible from different places. I have created kits for use at a wide range of latitudes, which you can download from https://in-the-sky.org/planisphere/ The planisphere presented in this document is designed for use at a latitude of 35◦N . What you need • Two sheets of A4 paper, or preferably thin card. • Scissors. • A split-pin fastener. • Optional: one sheet of transparent plastic, e.g. acetate designed for use with overhead projectors. • Optional: A little glue. Assembly instructions Step 1 { Planispheres look slightly different depending on where you live. The planisphere prepared in this document is designed for use anywhere on Earth which is within a few degrees of latitude 35◦N . If you live elsewhere, you should download an alternative kit from https://in-the-sky.org/planisphere/ Step 2 { Print the pages at the back of this PDF file, showing the star wheel and the body of the planisphere, onto two separate sheets of paper, or more preferably onto thin card.
