  • Celestial Navigation (Fall) NAME GROUP
    SIERRA COLLEGE OBSERVATIONAL ASTRONOMY LABORATORY EXERCISE Lab N03: Celestial Navigation (Fall) NAME GROUP OBJECTIVE: Learn about the Celestial Coordinate System. Learn about stellar designations. Learn about deep sky object designations. INTRODUCTION: The Horizon Coordinate System is simple, but flawed, because the altitude and azimuth measures of stars change as the sky rotates. Astronomers have developed an improved scheme called the Celestial Coordinate System, which is fixed with the stars. The two coordinates are Right Ascension and Declination. Declination ranges from the North Celestial Pole to the South Celestial Pole, with the Celestial Equator being a line around the sky at the midline of those two extremes. We will use these coordinates when navigating using the SC001 and SC002 charts. There are many ways to designate stars. The most common is called the Bayer designations. The Bayer designation of a star starts with a Greek letter. The brightest star in the constellation gets “alpha” (the first letter in the Greek alphabet), the second brightest star gets “beta,” and so on. (The Greek alphabet is shown below.) The Bayer designation must also include the constellation name. There are only 24 letters in the Greek alphabet, so this system is obviously very limited. The Greek alphabet 1) Alpha 7) Eta 13) Nu 19) Tau 2) Beta 8) Theta 14) Xi 20) Upsilon 3) Gamma 9) Iota 15) Omicron 21) Phi 4) Delta 10) Kappa 16) Pi 22) Chi 5) Epsilon 11) Lambda 17) Rho 23) Psi 6) Zeta 12) Mu 18) Sigma 24) Omega A more extensive naming system is called the Flamsteed designation.

The outcome will almost certainly be known before the next newsletter. For those of you not familiar with the project, the club has been offered an op- portunity to establish a base for both club and outreach events. Part of the pro- posal includes a permanent observing site, onsite storage, and possibly an ob- servatory down the road. In return, the club will provide an agreed upon number of outreach events and astronomy related support for the local school science programs.

  • Chasing the Pole — Howard L. Cohen
    Reprinted From AAC Newsletter FirstLight (2010 May/June) Chasing the Pole — Howard L. Cohen Polaris like supernal beacon burns, a pivot-gem amid our star-lit Dome ~ Charles Never Holmes (1916) ew star gazers often believe the North Star (Polaris) is brightest of all, even mistaking Venus for this best known star. More advanced star gazers soon learn dozens of Nnighttime gems appear brighter, forty-seven in fact. Polaris only shines at magnitude +2.0 and can even be difficult to see in light polluted skies. On the other hand, Sirius, brightest of all nighttime stars (at magnitude -1.4), shines twenty-five times brighter! Beginning star gazers also often believe this guidepost star faithfully defines the direction north. Although other stars staunchly circle the heavens during night’s darkness, many think this pole star remains steadfast in its position always marking a fixed point on the sky. Indeed, a popular and often used Shakespeare quote (from Julius Caesar) is in tune with this perception: “I am constant as the northern star, Of whose true-fix'd and resting quality There is no fellow in the firmament.” More advanced star gazers know better, that the “true-fix’d and resting quality”of the northern star is only an approximation. Not only does this north star slowly circle the northen heavenly pole (Fig. 1) but this famous star is also not quite constant in light, slightly varying about 0.03 magnitudes. Polaris, in fact, is the brightest appearing Cepheid variable, a type of pulsating star. Still, Polaris is a good marker of the north cardinal point.

  • A History of Star Catalogues
    A History of Star Catalogues © Rick Thurmond 2003 Abstract Throughout the history of astronomy there have been a large number of catalogues of stars. The different catalogues reflect different interests in the sky throughout history, as well as changes in technology. A star catalogue is a major undertaking, and likely needs strong justification as well as the latest instrumentation. In this paper I will describe a representative sample of star catalogues through history and try to explain the reasons for conducting them and the technology used. Along the way I explain some relevent terms in italicized sections. While the story of any one catalogue can be the subject of a whole book (and several are) it is interesting to survey the history and note the trends in star catalogues. 1 Contents Abstract 1 1.

  • Naming Objects in Thesky
    - ; Chapter 4 Naming ObjectS in TheSky Astronomers need to be able to assimilate and exchange information about specific objects in the sky. Many systems have been devised over the last few thousand years to identify and name the most conspicuous ones. As our technology has advanced, studies of astronomical objects have become more precise. Today it is common for astronomers to assign numerous designations to a single celestial body. Humans have observed the stars for millennia. Our ancestors named the bright stars as well as larger groups of stars called constellations. As we said in Chapter 1, the ancients named many of the constellations after mythological beasts, gods, demigods, and ordinary household objects. Astronomers continue to use the names of the constellations first recorded by ancient astronomers thousands of years ago. It is here that we may begin to learn about where things are located in the sky and how they are named. Astronomers officially recognize 88 distinct constellations today. TheSky displays all of them quite accurately. From the mid-northern latitudes, you can see over half of them. Most are visible every night from your location at some time during the night. TheSky helps you to find them but you must go outside on any clear night throughout the year and look for them yourself. About a half dozen or so constellations are visible every night from 40°north latitude all year round. These are the circumpolar constellations. They are all located in the northern sky near the North Star, Polaris. Using TheSky will definitely help you locate all these constellations easily during any season of the year.

University, Pozna´n,Poland 2Astronomical Institute, Slovak Academy of Sciences, 05960 Tatransk´aLomnica, Slovakia Abstract. During the General Assembly of the IAU in Beijing in 2012, at the business meeting of Commission 22 the list of 31 newly established showers was approved and next officially accepted by the IAU. As a result, at the end of2013, the list of all established showers contained 95 items. The IAU MDC Working List included 460 meteor showers, among them 95 had pro tempore status. The List of Shower Groups contained 24 com- plexes, three of them had established status. Jointly, the IAU MDC shower database contained data of 579 showers. Keywords: established meteor showers, IAU MDC, meteor database, meteor showers nomenclature 1. Introduction Since its establishing, the activity of the Task Group of Meteor Shower Nomencla- ture (later transformed into the Working Group on Meteor Shower Nomenclature, hereafter WG) proved to be advisable.y As results of this activity, several practical principles (rules) have been adopted: { the meteor shower codes and naming conventions (Jenniskens 2006a, 2007, 2008; Jopek and Jenniskens 2011), { a two-step process was established, where all new showers discussed in literature are first added to the Working List of Meteor Showers, each being assigned a unique name, a number, and a three letter code, { all showers which satisfy the verification criterion will be included in the List of Established Showers and then officially accepted during next GA IAU.

  • Ast 11 Prelab Lab 10: Introduction to the Stars [Note: Header with Title]
    Ast 11 Prelab Lab 10: Introduction to the Stars [Note: header with title] Barry Rice, Table C 14 September 2018 Section: Tuesday/Thursday, 11:00-12:05 [Note: name, table, date, section] Introduction and Purpose [Note: overall summary of what the lab is about] Stars in the sky are grouped in regions called constellations. Individual stars are named by their Bayer designation or by their Flamsteed designation. Their brightnesses are indicated by their magnitudes. We will find three specific stars in the sky, in three different constellations. The angular distances between the stars are measured in degrees, arcminutes, and arcseconds. Procedure I [Note: this gives a clear step-by-step explanation of the key lab steps] 1. We will find and label the three stars on the star map, then label and highlight the constellation boundaries that contain the stars; 2. We will use a program to determine the star’s Bayer and Flamsteed designations, then also their magnitudes; 3. We will measure the angular width of our hand-span, fist, 3-fingers, and pinkie (Table C); Procedure II 4. At night, we will find the three stars, and measure the separation between the stars (Tables D, E), using the hand measures we calibrated in class. Vocabulary [Note: One line definitions of all the terms given in the vocabulary list in the lab.] Constellation—An official grouping of stars in the sky, and the boundaries that contains them. Example: Ursa major. Asterism—an unofficial grouping of stars in the sky. Example: Big Dipper. Linear measure—distances on a map, measured in meters, centimeters, or millimeters, etc.

For deep sky objects “M” designates Messier List object, “C” Caldwell List Object, “NGC” New General Catalogue, “IC” Index Catalogue for nebulae, and “Mel” for Melotte Open Cluster Catalogue. For stars, I give the proper names (spellings may vary) or nicknames, plus Bayer designation (Greek letter plus Latin constellation name) and/or Flamsteed designation (numeral and Latin constellation name), and the visual magnitude “mag”. For doubles/multiples I have provided mags, separations “sep” in minutes (‘) or seconds (“), colours, etc. No nebulae this month! Leo (Leonis) and Virgo (Virginis) Algieba (Gamma Leonis) – pretty pair of yellow stars (mags 2.6 and 3.8, sep. 4.5”) easily split Quasar 3C 273 – Brightest quasar, challenge at mag 12.89, in Virgo, 2.4 Billion LY away! 3.5° NE of 15 Virginis Coma Berenices (Comae Berenices) North Galactic Pole (NGP) – situated near the star 31 Com. Many galaxies are observable in this region of sky because we are looking through less of the Milky Way. (The south galactic pole (SGP) is in Sculptor, near NGC288. There are far fewer galaxies in that direction.) Black-Eye Galaxy / M64 / NGC4826 – Bright mag 8.5 spiral galaxy with a bright core surrounded by a dark rim.

It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy A giant Hubble mosaic of the Crab Nebula, a supernova remnant has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics.
