Greenwich Mean Time, identifies the time zone of reference of the Earth. If we divide the 360° for 24 to obtain a 24 parts each 15° longitude, in reality the realm is bounded by nationwide borders. Are the date, the values are selectable by combo, the default is at present. The length of the shadow map is normalized , and the direction is opposite azimuth. Try decreasing the number of spacecraft chosen if the map is slow to respond. Printed on museum grade artwork matte paper and printed utilizing archival inks.

It is a planisphere depicting the zodiac in graphical representations. Multiple stars may bear the same letter and be distinguished by a numeric subscript.
