    Thanet Astronomy Group Astronomy for Everyone in Plain English What to see December 29th Constellation (Orion) Stars (Betelguese, Bellatrix, Alnitak, Alnilam, Mintaka, Rigel, Saiph,) Asterism (The Winter Triangle) Stars (Betelguese, Sirius, Procyon) November to March the constellation Orion the Hunter is at its best. There are some 20 prominent stars in this constellation. The brightest and more easily observed stars are the 8 in the main body. The other stars form Orion's right arm with club, and a slain animal in his left hand. These stars are dimmer and difficult to see due to light pollution. At 8:00pm Looking South East at 119° up to 30° you see the star Betelguese, the top left corner of Orion, a red super giant, more than 1½ billion kms in diameter. Look at 127° up to 33° you see the star Bellatrix, the top right corner of Orion, at 8½ million kms in diameter. Look at 128° down to 24° you see Alnitak, the first of three stars side by side, forming Orion's belt. Alnitak, Alnilam (at 128° 25°) and Mintaka (at 129° 26°). Probably one of the more easily recognised groups of stars in this area of sky. Look at 137° down to 21° you see the star Rigel, the bottom right corner of Orion. A blue/white super giant, 108 million kms in diameter. Look at 130° down to 16° you see the star Saiph the bottom left corner of Orion, nearly 31 million kms in diameter.

  • Requirements of Timely Performance in Time and Voyage Charterparties
    Graduate School REQUIREMENTS OF TIMELY PERFORMANCE IN TIME AND VOYAGE CHARTERPARTIES - AN EXPLORATION OF THEIR IDENTITY, SCOPE AND LIMITATIONS UNDER ENGLISH LAW Thesis submitted for the degree of Doctor of Philosophy at the University of Leicester by Tamaraudoubra Tom Egbe School of Law University of Leicester 2019 Abstract REQUIREMENTS OF TIMELY PERFORMANCE IN TIME AND VOYAGE CHARTERPARTIES - AN EXPLORATION OF THEIR IDENTITY, SCOPE AND LIMITATIONS UNDER ENGLISH LAW By Tamaraudoubra Tom Egbe The importance of time in the performance of contractual obligations under sea carriage of goods arrangements are until now little explored. For the avoidance of breach, certain obligations and responsibilities of the parties to the contract need to be performed promptly. Ocean transport is an expensive venture and a shipowner could suffer considerable financial losses if an unnecessary but serious delay interrupt the vessel’s earning power in the course of the charterer’s performance of his contractual obligation. On the other hand, a charterer could also incur a substantial loss if arrangements for the shipment and receipt of cargo fail to go according to plan as a result of the shipowner’s failure to perform his charterparty obligation timely and with reasonable diligence. With these considerations in mind, this thesis critically explores the concept of timely performance in the discharge of the contractual obligations of parties to a contract of carriage. While the thesis is not an expository of the occurrence of time in all the obligations of parties to the carriage contract, it focusses particularly on the identity, scope, and limitations of timeliness in the context of timely payment of hire, laytime and reasonable despatch.

  • A Method for Identifying the Pleiades Star Cluster in a Khipu From
    Saez-Rodríguez. A. (2012). An Ethnomathematics Exercise for Analyzing a Khipu Sample from Pachacamac (Perú). Revista Latinoamericana de Etnomatemática. 5(1). 62-88 Artículo recibido el 1 de diciembre de 2011; Aceptado para publicación el 30 de enero de 2012 An Ethnomathematics Exercise for Analyzing a Khipu Sample from Pachacamac (Perú) Ejercicio de Etnomatemática para el análisis de una muestra de quipu de Pachacamac (Perú) Alberto Saez-Rodríguez1 Abstract A khipu sample studied by Gary Urton embodies an unusual division into quarters. Urton‟s research findings allow us to visualize the information in the pairing quadrants, which are determined by the distribution of S- and Z-knots, to provide overall information that is helpful for identifying the celestial coordinates of the brightest stars in the Pleiades cluster. In the present study, the linear regression attempts to model the relationship between two variables (which are determined by the distribution of the S- and Z-knots). The scatter plot illustrates the results of our simple linear regression: suggesting a map of the Pleiades represented by seven points on the Cartesian coordinate plane. Keywords: Inca khipu, Linear regression analysis, Celestial coordinate system, Pleiades. Resumen Una muestra de quipu estudiada por Gary Urton comporta una división por cuadrantes poco común. Utilizando dicho hallazgo de Urton, podemos visualizar la información contenida en los pares de cuadrantes, la cual está determinada por una distribución de nudos con orientaciones opuestas de „S‟ y de „Z‟, brindándonos, así, toda la información necesaria para identificar las coordenadas celestes de las estrellas más brillantes del cúmulo de las Pléyades. En el presente estudio se usa el análisis de la Regresión Lineal con el fin de construir un modelo que permita predecir el comportamiento de la variable dependiente y (valores de los nudos con orientación de „Z‟) en función de la variable independiente x (valores de los nudos con orientación de „S‟).

    Extraterrestrial places in the Cthulhu Mythos 1.1 Abbith A planet that revolves around seven stars beyond Xoth. It is inhabited by metallic brains, wise with the ultimate se- crets of the universe. According to Friedrich von Junzt’s Unaussprechlichen Kulten, Nyarlathotep dwells or is im- prisoned on this world (though other legends differ in this regard). 1.2 Aldebaran Aldebaran is the star of the Great Old One Hastur. 1.3 Algol Double star mentioned by H.P. Lovecraft as sidereal The double star Algol. This infrared imagery comes from the place of a demonic shining entity made of light.[1] The CHARA array. same star is also described in other Mythos stories as a planetary system host (See Ymar). The following fictional celestial bodies figure promi- nently in the Cthulhu Mythos stories of H. P. Lovecraft and other writers. Many of these astronomical bodies 1.4 Arcturus have parallels in the real universe, but are often renamed in the mythos and given fictitious characteristics. In ad- Arcturus is the star from which came Zhar and his “twin” dition to the celestial places created by Lovecraft, the Lloigor. Also Nyogtha is related to this star. mythos draws from a number of other sources, includ- ing the works of August Derleth, Ramsey Campbell, Lin Carter, Brian Lumley, and Clark Ashton Smith. 2 B Overview: 2.1 Bel-Yarnak • Name.

The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris. Check with binoculars. © Rob Peeling, CaDAS, 2007 version 2.0 Wynyard Planetarium & Observatory PUBLIC OBSERVING – Winter Polaris, Kochab and Pherkad mark the constellation Ursa Minor, the Little Bear.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.

  • A Basic Requirement for Studying the Heavens Is Determining Where In
    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).
