Basic Principles of Celestial Navigation James A
Basic principles of celestial navigation James A. Van Allena) Department of Physics and Astronomy, The University of Iowa, Iowa City, Iowa 52242 ͑Received 16 January 2004; accepted 10 June 2004͒ Celestial navigation is a technique for determining one’s geographic position by the observation of identified stars, identified planets, the Sun, and the Moon. This subject has a multitude of refinements which, although valuable to a professional navigator, tend to obscure the basic principles. I describe these principles, give an analytical solution of the classical two-star-sight problem without any dependence on prior knowledge of position, and include several examples. Some approximations and simplifications are made in the interest of clarity. © 2004 American Association of Physics Teachers. ͓DOI: 10.1119/1.1778391͔ I.

Concrete Prehistories: the Making of Megalithic Modernism 1901-1939
Concrete Prehistories: The Making of Megalithic Modernism Abstract After water, concrete is the most consumed substance on earth. Every year enough cement is produced to manufacture around six billion cubic metres of concrete1. This paper investigates how concrete has been built into the construction of modern prehistories. We present an archaeology of concrete in the prehistoric landscapes of Stonehenge and Avebury, where concrete is a major component of megalithic sites restored between 1901 and 1964. We explore how concreting changed between 1901 and the Second World War, and the implications of this for constructions of prehistory. We discuss the role of concrete in debates surrounding restoration, analyze the semiotics of concrete equivalents for the megaliths, and investigate the significance of concreting to interpretations of prehistoric building. A technology that mixes ancient and modern, concrete helped build the modern archaeological imagination. Concrete is the substance of the modern –”Talking about concrete means talking about modernity” (Forty 2012:14). It is the material most closely associated with the origins and development of modern architecture, but in the modern era, concrete has also been widely deployed in the preservation and display of heritage. In fact its ubiquity means that concrete can justifiably claim to be the single most dominant substance of heritage conservation practice between 1900 and 1945. This paper investigates how concrete has been built into the construction of modern pasts, and in particular, modern prehistories. As the pre-eminent marker of modernity, concrete was used to separate ancient from modern, but efforts to preserve and display prehistoric megaliths saw concrete and megaliths become entangled. -

Researching Stonehenge: Theories Past and Present
Parker Pearson, M 2013 Researching Stonehenge: Theories Past and Present. Archaeology International, No. 16 (2012-2013): 72-83, DOI: http://dx.doi.org/10.5334/ai.1601 ARTICLE Researching Stonehenge: Theories Past and Present Mike Parker Pearson* Over the years archaeologists connected with the Institute of Archaeology and UCL have made substantial contributions to the study of Stonehenge, the most enigmatic of all the prehistoric stone circles in Britain. Two of the early researchers were Petrie and Childe. More recently, colleagues in UCL’s Anthropology department – Barbara Bender and Chris Tilley – have also studied and written about the monument in its landscape. Mike Parker Pearson, who joined the Institute in 2012, has been leading a 10-year-long research programme on Stonehenge and, in this paper, he outlines the history and cur- rent state of research. Petrie and Childe on Stonehenge William Flinders Petrie (Fig. 1) worked on Stonehenge between 1874 and 1880, publishing the first accurate plan of the famous stones as a young man yet to start his career in Egypt. His numbering system of the monument’s many sarsens and blue- stones is still used to this day, and his slim book, Stonehenge: Plans, Descriptions, and Theories, sets out theories and observations that were innovative and insightful. Denied the opportunity of excavating Stonehenge, Petrie had relatively little to go on in terms of excavated evidence – the previous dig- gings had yielded few prehistoric finds other than antler picks – but he suggested that four theories could be considered indi- vidually or in combination for explaining Stonehenge’s purpose: sepulchral, religious, astronomical and monumental. -

Phases of the Moon by Patti Hutchison
Phases of the Moon By Patti Hutchison 1 Was there a full moon last night? Some people believe that a full moon affects people's behavior. Whether that is true or not, the moon does go through phases. What causes the moon to appear differently throughout the month? 2 You know that the moon does not give off its own light. When we see the moon shining at night, we are actually seeing a reflection of the Sun's light. The part of the moon that we see shining (lunar phase) depends on the positions of the sun, moon, and the earth. 3 When the moon is between the earth and the sun, we can't see it. The sunlit side of the moon is facing away from us. The dark side is facing toward us. This phase is called the new moon. 4 As the moon moves along its orbit, the amount of reflected light we see increases. This is called waxing. At first, there is a waxing crescent. The moon looks like a fingernail in the sky. We only see a slice of it. 5 When it looks like half the moon is lighted, it is called the first quarter. Sounds confusing, doesn't it? The quarter moon doesn't refer to the shape of the moon. It is a point of time in the lunar month. There are four main phases to the lunar cycle. Four parts- four quarters. For each of these four phases, the moon has orbited one quarter of the way around the earth. -

Technical Memorandum To: Thaddeus Johnson, Jessica Kronenwetter, Kevin Work, William Chadwick, Brian Middleton, Kevin Ludlum, and Seth Iacangelo (NOAA/OSPO, GOES-R/MOST) From: Fangfang Yu, Xiangqian Wu and Xi Shao (NOAA/STAR) Subject: ABI Lunar Trending Image Collection Requirements in the Operational Period Date: 05/01/2018 Rev: Rev 2.0 Cc: Jon Fulbright (NOAA GOES-R/PRO) This technical memo lists the set of lunar trending requirements for the GOES-16 ABI operational period, which can be summarized as followed: Scan pattern: (1) the unclipped Moon can be scanned with either MESO1 or MESO2; and (2) the Moon should be located near the center of the MESO swath at the north-south direction for all the ABI bands. Location: (1) the Moon should appear within the ABI field of regard (FOR); (2) the center of the Moon should be at least 0.013 radians away from the Earth limb for all the ABI bands; and (3) the edge of the Moon should be at least 0.002 radians away from the MESO frame boundary at the east-west direction. Frequency per month: 2-4 trending events per lunar phase. Phase Angle Range: (1) the highest priority two lunar trending events shall have the smallest absolute phase angle as possible between Earth and Moon, but not less than 5.0 degrees. These two trending events shall be on opposite sides of the Earth. (2). The other two lunar trending events with relatively lower priority shall have an absolute phase angle as close as possible to 60 degrees between Earth and Moon, but not more than 90.0 degrees. -

In order to parameterize the detector for such a newly-proposed MERO, the evaluation of the instrument’s entrance pupil irradiance (EPI) is of great importance. The motivation of this work is to build an EPI estimating model for a simplified single-pixel MERO instrument. The rationale of this model is to sum the contributions of every location in the MERO-viewed region on the Earth’s top of atmosphere (TOA) to the MERO sensor’s EPI, taking into account the anisotropy in the longwave radiance at the Earth TOA. Such anisotropy could be characterized by the TOA anisotropic factors, which can be derived from the Clouds and the Earth’s Radiant Energy System (CERES) angular distribution models (ADMs). -
Stonehenge and Ancient Astronomy Tonehenge Is One of the Most Impressive and Best Known Prehistoric Stone Monuments in the World
Stonehenge and Ancient Astronomy tonehenge is one of the most impressive and best known prehistoric stone monuments in the world. Ever since antiquarians’ accounts began to bring the site to wider attention inS the 17th century, there has been endless speculation about its likely purpose and meaning, and a recurring theme has been its possible connections with astronomy and the skies. was it a Neolithic calendar? A solar temple? A lunar observatory? A calculating device for predicting eclipses? Or perhaps a combination of more than one of these? In recent years Stonehenge has become the very icon of ancient astronomy, featuring in nearly every discussion on the subject. And yet there are those who persist in believing that it actually had little or no connection with astronomy at all. A more informed picture has been obtained in recent years by combining evidence from archaeology and astronomy within the new interdiscipline of archaeoastronomy – the study of beliefs and practices concerning the sky in the past and the uses to which people’s knowledge of the skies were put. This leaflet attempts to summarize the evidence that the Stonehenge monument was constructed by communities with a clear interest in the sky above them. Photograph: Stonehenge in the snow.
