Summer Constellations
Night Sky 101: Summer Constellations The Summer Triangle Photo Credit: Smoky Mountain Astronomical Society The Summer Triangle is made up of three bright stars—Altair, in the constellation Aquila (the eagle), Deneb in Cygnus (the swan), and Vega Lyra (the lyre, or harp). Also called “The Northern Cross” or “The Backbone of the Milky Way,” Cygnus is a horizontal cross of five bright stars. In very dark skies, Cygnus helps viewers find the Milky Way. Albireo, the last star in Cygnus’s tail, is actually made up of two stars (a binary star). The separate stars can be seen with a 30 power telescope. The Ring Nebula, part of the constellation Lyra, can also be seen with this magnification. In Japanese mythology, Vega, the celestial princess and goddess, fell in love Altair. Her father did not approve of Altair, since he was a mortal. They were forbidden from seeing each other. The two lovers were placed in the sky, where they were separated by the Celestial River, repre- sented by the Milky Way. According to the legend, once a year, a bridge of magpies form, rep- resented by Cygnus, to reunite the lovers. Photo credit: Unknown Scorpius Also called Scorpio, Scorpius is one of the 12 Zodiac constellations, which are used in reading horoscopes. Scorpius represents those born during October 23 to November 21. Scorpio is easy to spot in the summer sky. It is made up of a long string bright stars, which are visible in most lights, especially Antares, because of its distinctly red color. Antares is about 850 times bigger than our sun and is a red giant.

You may have noticed that this newsletter is showing up a little bit later than usual, and it’s for good reason: release of the newsletter will now happen after the monthly business meeting so that we can have a chance to keep everybody up to date on the latest information. Sometimes, this will mean the newsletter shows up a couple of days late. But, the upshot is that you’ll now be able to see what we discussed at the recent business meeting and have time to digest it before our general meeting in case you want to give some feedback. Now that we’re on the new format, business meetings (and the oft neglected Light Pollution Committee Meeting), are going to start being open to all members of the club again by simply joining up in the respective chat rooms the Wednesday before the first Monday of the month—which I encourage people to do, especially if you have some ideas you want to see the club put into action.

IAU Division C Working Group on Star Names 2019 Annual Report
IAU Division C Working Group on Star Names 2019 Annual Report Eric Mamajek (chair, USA) WG Members: Juan Antonio Belmote Avilés (Spain), Sze-leung Cheung (Thailand), Beatriz García (Argentina), Steven Gullberg (USA), Duane Hamacher (Australia), Susanne M. Hoffmann (Germany), Alejandro López (Argentina), Javier Mejuto (Honduras), Thierry Montmerle (France), Jay Pasachoff (USA), Ian Ridpath (UK), Clive Ruggles (UK), B.S. Shylaja (India), Robert van Gent (Netherlands), Hitoshi Yamaoka (Japan) WG Associates: Danielle Adams (USA), Yunli Shi (China), Doris Vickers (Austria) WGSN Website: https://www.iau.org/science/scientific_bodies/working_groups/280/ WGSN Email: [email protected] The Working Group on Star Names (WGSN) consists of an international group of astronomers with expertise in stellar astronomy, astronomical history, and cultural astronomy who research and catalog proper names for stars for use by the international astronomical community, and also to aid the recognition and preservation of intangible astronomical heritage. The Terms of Reference and membership for WG Star Names (WGSN) are provided at the IAU website: https://www.iau.org/science/scientific_bodies/working_groups/280/. WGSN was re-proposed to Division C and was approved in April 2019 as a functional WG whose scope extends beyond the normal 3-year cycle of IAU working groups. The WGSN was specifically called out on p. 22 of IAU Strategic Plan 2020-2030: “The IAU serves as the internationally recognised authority for assigning designations to celestial bodies and their surface features. To do so, the IAU has a number of Working Groups on various topics, most notably on the nomenclature of small bodies in the Solar System and planetary systems under Division F and on Star Names under Division C.” WGSN continues its long term activity of researching cultural astronomy literature for star names, and researching etymologies with the goal of adding this information to the WGSN’s online materials.

Astronomical Coordinate Systems
Appendix 1 Astronomical Coordinate Systems A basic requirement for studying the heavens is being able to determine where in the sky things are located. To specify sky positions, astronomers have developed several coordinate systems. Each sys- tem uses a coordinate grid projected on the celestial sphere, which is similar to the geographic coor- dinate 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 The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the most closely related to the geographic coordinate system because they use the same funda- mental plane and poles. The projection of the Earth’s equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles onto the celestial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate sys- tems: the geographic system is fixed to the Earth and 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 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.

Received 2018 November 7; in original form 2018 April 6 ABSTRACT We have initiated a dedicated project to follow-up with ground-based photometry the transiting planets discovered by CoRoT in order to reﬁne the orbital elements, constrain their physical parameters, and search for additional bodies in the system. From 2012 September to 2016 December we carried out 16 transit observations of six CoRoT planets (CoRoT-5 b, CoRoT- 8 b, CoRoT-12 b, CoRoT-18 b, CoRoT-20 b, and CoRoT-27 b) at three observatories located in Germany and Spain. These observations took place between 5 and 9 yr after the planet’s discovery, which has allowed us to place stringent constraints on the planetary ephemeris.

An Aboriginal Australian Record of the Great Eruption of Eta Carinae
Accepted in the ‘Journal for Astronomical History & Heritage’, 13(3): in press (November 2010) An Aboriginal Australian Record of the Great Eruption of Eta Carinae Duane W. Hamacher Department of Indigenous Studies, Macquarie University, NSW, 2109, Australia [email protected] David J. Frew Department of Physics & Astronomy, Macquarie University, NSW, 2109, Australia [email protected] Abstract We present evidence that the Boorong Aboriginal people of northwestern Victoria observed the Great Eruption of Eta (η) Carinae in the nineteenth century and incorporated the event into their oral traditions. We identify this star, as well as others not specifically identified by name, using descriptive material presented in the 1858 paper by William Edward Stanbridge in conjunction with early southern star catalogues. This identification of a transient astronomical event supports the assertion that Aboriginal oral traditions are dynamic and evolving, and not static. This is the only definitive indigenous record of η Carinae’s outburst identified in the literature to date. Keywords: Historical Astronomy, Ethnoastronomy, Aboriginal Australians, stars: individual (η Carinae). 1 Introduction Aboriginal Australians had a significant understanding of the night sky (Norris & Hamacher, 2009) and frequently incorporated celestial objects and transient celestial phenomena into their oral traditions, including the sun, moon, stars, planets, the Milky Way and Magellanic Clouds, eclipses, comets, meteors, and impact events. While Australia is home to hundreds of Aboriginal groups, each with a distinct language and culture, few of these groups have been studied in depth for their traditional knowledge of the night sky. We refer the interested reader to the following reviews on Australian Aboriginal astronomy: Cairns & Harney (2003), Clarke (1997; 2007/2008), Fredrick (2008), Haynes (1992; 2000), Haynes et al.

CoRoT at- tempts to observe the transits of these planets accross their parent stars. CoRoT occupies an orbit which periodically carries it through the Van Allen Belts, resulting in a a very high level of high outliers in the flux data. Known systematics and out- liers were removed from the data and the remaining scatter was evaluated using the median of abolute deviations from the median (MAD), a measure of scatter which is robust to outliers. The level of scatter (evaluated with MAD) present in this data is indicative of the lower limits on the size of planets detectable by CoRoT or a similar satellite. The MAD for CoRoT stars is correlated with the magnitude.

Among the Inuit, there is a huge difference in spelling and pronunciation. In the old days before a written language existed this can a.o. be credited to or blamed on the travelers who wrote the legends and stories down. Today there are several dictionaries, each cover- ing its own area. Words and spelling in this text are mainly taken directly from ”The Arctic Sky”, and only occasionally supplemented with modern spellings, mainly from Greenland.

Constellation Legends
Constellation Legends by Norm McCarter Naturalist and Astronomy Intern SCICON Andromeda – The Chained Lady Cassiopeia, Andromeda’s mother, boasted that she was the most beautiful woman in the world, even more beautiful than the gods. Poseidon, the brother of Zeus and the god of the seas, took great offense at this statement, for he had created the most beautiful beings ever in the form of his sea nymphs. In his anger, he created a great sea monster, Cetus (pictured as a whale) to ravage the seas and sea coast. Since Cassiopeia would not recant her claim of beauty, it was decreed that she must sacrifice her only daughter, the beautiful Andromeda, to this sea monster. So Andromeda was chained to a large rock projecting out into the sea and was left there to await the arrival of the great sea monster Cetus. As Cetus approached Andromeda, Perseus arrived (some say on the winged sandals given to him by Hermes). He had just killed the gorgon Medusa and was carrying her severed head in a special bag. When Perseus saw the beautiful maiden in distress, like a true champion he went to her aid. Facing the terrible sea monster, he drew the head of Medusa from the bag and held it so that the sea monster would see it. Immediately, the sea monster turned to stone. Perseus then freed the beautiful Andromeda and, claiming her as his bride, took her home with him as his queen to rule. Aquarius – The Water Bearer The name most often associated with the constellation Aquarius is that of Ganymede, son of Tros, King of Troy.
