The electronic solar globe is a three-dimensional precision instrument which can be rotated and inclined in any direction and realistically reproduces over 20000 eclipses in a period of 10000 years. Solar globe with eclipse phases, protruberances, string-of-pearl phenomena and corona. Course of eclipse in REAL TIME with advancing date and time announcement, refered to world time or dynamic time. Starting from the date input, the next 22 eclipses may be chosen. The entire course of the eclipse region and zone of totality is reproduced on the terrestrial globe (with day/night side and twilight zone), the world map and fundamental plane, with migrating umbras and penumbras of the moon. Accuracy of the solar and lunar position: 1 arc second. All technical and physical data can be called up using panels which can be switched over in each case; data such as geographical longitude and latitude of the central line, eclipse duration etc. Solar rotation with sporadically occurring sun spots. In addition: grids of parallels and meridians, city names which can be called up, 4 enlargements and two extensions of the celestial segment with stars and planets (inform. by means of switching on) and reproduction of all the passes of mercury and venus. The space globe is self-explanatory. The accompanying text contains historical solar eclipses, which can be reproduced by inputting date and time, as well as extensive explanations of the production of the eclipses, sun spots and more.
