Explore the Universe Observing Certificate Second Edition
RASC Observing Committee Explore the Universe Observing Certificate Second Edition Explore the Universe Observing Certificate Welcome to the Explore the Universe Observing Certificate Program. This program is designed to provide the observer with a well-rounded introduction to the night sky visible from North America. Using this observing program is an excellent way to gain knowledge and experience in astronomy. Experienced observers find that a planned observing session results in a more satisfying and interesting experience. This program will help introduce you to amateur astronomy and prepare you for other more challenging certificate programs such as the Messier and Finest NGC. The program covers the full range of astronomical objects. Here is a summary: Observing Objective Requirement Available Constellations and Bright Stars 12 24 The Moon 16 32 Solar System 5 10 Deep Sky Objects 12 24 Double Stars 10 20 Total 55 110 In each category a choice of objects is provided so that you can begin the certificate at any time of the year. In order to receive your certificate you need to observe a total of 55 of the 110 objects available. Here is a summary of some of the abbreviations used in this program Instrument V – Visual (unaided eye) B – Binocular T – Telescope V/B - Visual/Binocular B/T - Binocular/Telescope Season Season when the object can be best seen in the evening sky between dusk. and midnight. Objects may also be seen in other seasons. Description Brief description of the target object, its common name and other details. Cons Constellation where object can be found (if applicable) BOG Ref Refers to corresponding references in the RASC’s The Beginner’s Observing Guide highlighting this object. -
The Observer's Handbook for 1912
T he O bservers H andbook FOR 1912 PUBLISHED BY THE ROYAL ASTRONOMICAL SOCIETY OF CANADA E d i t e d b y C. A, CHANT FOURTH YEAR OF PUBLICATION TORONTO 198 C o l l e g e St r e e t Pr in t e d fo r t h e So c ie t y 1912 T he Observers Handbook for 1912 PUBLISHED BY THE ROYAL ASTRONOMICAL SOCIETY OF CANADA TORONTO 198 C o l l e g e St r e e t Pr in t e d fo r t h e S o c ie t y 1912 PREFACE Some changes have been made in the Handbook this year which, it is believed, will commend themselves to observers. In previous issues the times of sunrise and sunset have been given for a small number of selected places in the standard time of each place. On account of the arbitrary correction which must be made to the mean time of any place in order to get its standard time, the tables given for a particualar place are of little use any where else, In order to remedy this the times of sunrise and sunset have been calculated for places on five different latitudes covering the populous part of Canada, (pages 10 to 21), while the way to use these tables at a large number of towns and cities is explained on pages 8 and 9. The other chief change is in the addition of fuller star maps near the end. These are on a large enough scale to locate a star or planet or comet when its right ascension and declination are given. -
Wojciech Roszkowski Post-Communist Lustration in Poland: a Political and Moral Dilemma Congress of the Societas Ethica, Warsaw 22 August 2009 Draft Not to Be Quoted
Wojciech Roszkowski Post-Communist Lustration in Poland: a Political and Moral Dilemma Congress of the Societas Ethica, Warsaw 22 August 2009 Draft not to be quoted 1. Introduction Quite recently a well-known Polish writer stated that the major dividing line in the Polish society runs across the attitude towards lustration. Some Poles, he said, have been secret security agents or collaborators or, for some reasons, defend this cooperation, others have not and want to make things clear1. Even if this statement is a bit exaggerated, it shows how heated the debates on lustration in Poland are. Secret services in democratic countries are a different story than security services in totalitarian states. Timothy Garton Ash even calls this comparison “absurd”2. A democratic state is, by definition, a common good of its citizens. Some of them are professionals dealing with the protection of state in police, armed forces and special services, all of them being subordinated to civilian, constitutional organs of the state. Other citizens are recruited by these services extremely rarely and not without their consent. In totalitarian states secret services are the backbone of despotic power of the ruling party and serve not the security of a country but the security of the ruling elites. Therefore they should rather be given the name of security services. They tend to bring under their control all aspects of political, social, economic, and cultural life of the subjects of the totalitarian state, becoming, along with uniformed police and armed forces, a pillar of state coercion. Apart from propaganda, which is to make people believe in the ideological goals of the totalitarian state, terror is the main vehicle of power, aiming at discouraging people from any thoughts and deeds contrary to the said goals and even from any activity independent of the party-state. -

Out of the and the pulsar’s moment of inertia (I) must be 5670 plots, three known pulsars were found and determined.

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr. -

What's In This Issue? Astro Short- Mercury: Snow Globe Dynamo? Secretary's Summary Message From HRPO Globe At Night Recent Forum Entries Orion Exploration Test Flight Event International Year of Light 20/20 Vision Campaign Observing Notes by John Nagle Mercury: Snow Globe Dynamo? We already knew Mercury was bizarre. A planet of extremes, during its day facing the sun, its surface temperature tops 800°F —hot enough to melt lead—but during the night, the temperature plunges to -270°F, way colder than dry ice. Frozen water may exist at its poles. And its day (from sunrise to sunrise) is twice as long as its year. Now add more weirdness measured by NASA’s recent MESSENGER spacecraft: Mercury’s magnetic field in its northern hemisphere is triple its strength in the southern hemisphere. Numerical models run by postdoctoral researcher Hao Cao, working in the lab of Christopher T. Russell at UC Los Angeles, offer an explanation: inside Mercury’s molten iron core it is “snowing,” and the resultant convection is so powerful it causes the planet’s magnetic dynamo to break symmetry and concentrate in one hemisphere. “Snowing” inside Mercury With a diameter only 40 percent greater than the Moon’s, Mercury is the smallest planet in the solar system (now that Pluto was demoted). But its gravitational field is more than double the Moon’s.
