The last three years have been marked by changes, highlights and progress. Organizationally, commission 7 has joined Division I and plans proceed for commissions 8 and 24 to merge in 2000. They have had a common vice president during this triennium. Sadly, the Royal Greenwich Observatory was closed after over 200 years, but Her Majesty’s Nautical Almanac Office has continued at Rutherford Appleton Laboratory. In St Petersburg, Russia, the Institute of Theoretical Astronomy was abolished, with some of the personnel relocated to the Institute of Applied Astronomy and Pulkova Observatory. In Pari

Abstract:
In this technological age, when anartistof nautical astronomy is fast becoming a figure of history, there is a tendency to regard astro-navigation as something that went out with the dodo. It would be as well to remember, therefore, that despite the widespread use of radio navaids from the early years of World War II, astronomical navigation remained the only world-wide fixing system until the launch of the Transit navigation satellites during the 1960s. The truth is that the first half of the present century saw enormous advances in both its methods and practice and the fact that it is still

Abstract:
The universe of marine navigators and surveyors is basically a geocentric one. All calculations necessary for reducing celestial observations to obtain directional or positional information can be carried out within the pre- Copernican two sphere hypothesis. Some mature students on the degree courses have practical experience of navigation at sea but are not used to more abstract ways of thinking. However, most courses in navigation require students to understand the many corrections that have to be applied in astro-navigation. The planetarium can be used to illustrate the basic concepts of th

Abstract:
Of the great oceans of the world, the Atlantic, because of its violence, was the last to be mastered by man. The task in its entirety had to wait for the Portuguese sailors of the Renaissance. Isidore of Seville (c. 570–636), a Christian writer of the late Roman Empire, had written of the Atlantic that it was ‘incommensurable and uncrossable’. Although Pliny (a.d. 23–79) refers vaguely to the Canary Islands, all knowledge of them disappears in the Middle Ages until a Portuguese expedition under the command of the Italian Lanzarotto Malocello ‘re- discovered’ them in 1336.

Abstract:
A escrita da história da astronomia foi conduzida por alguns pontos chaves: a relação deste saber com as viagens de expansão e o aprimoramento da náutica, a diferenciação da astrologia e o questionamento do lugar da ciência e da superstição para o estudo do céu, bem como a construção das estruturas deste saber pelos escritos que desdobraram o assunto. Todas estas tópicas foram desenvolvidas em maior ou menor grau nos estudos historiográficos das décadas passadas que trataram da ciência do céu.

Abstract:
It is believed that Vasco da Gama carried nautical tables on his first voyage to the Indies, 1497–1499, that had especially been produced for the years 1497–1500 by Abraham Zacut, then Royal Astronomer in the service of the Portuguese court. Maritime history writers have suggested two manuscripts as surviving copies of these da Gama tables. One of them is a set of declination tables in the 1519 edition of Suma de Geographia by Martín Fernández de Enciso. Analysis of all available data shows that these tables are indeed good candidates, though their production from the 1505–1508 astronomical ta

Fajr in syar’i concept is divided into two; Fajr Kazib and Fajar Shadiq. The Fajr Kazib is time to having breakfast before doing fasting and have no salah Subuh. The second is fajr Shadiq. It is time to have no having meal (because it is fasting time) and time to do salah Subuh. Fajr Kazib arises at the early morning whose the light is not bright, but it is longer to the top of East to West vertically. Then the sky comes dark like wolf tail.

Abstract:
This paper explores Aristotle's remarks in Posterior Analytics on certain special disciplines that are subordinate to pure mathematical sciences. Optics, harmonics and mechanics prove their own contents by means of premises belonging to arithmetic or geometry. Even though subaltern sciences are exceptions to the prohibition on kind crossing, the premises to their demonstrations are legitimately appropriate to the relative conclusions. In order to delineate the demonstrative structure of subordinate sciences, Aristotle introduces the distinction between knowledge of a fact and knowledge of the
