Map notes

• The day and night parts of the Earth shown are as of Saturday, May 19, 2012 at 04:18:00 UTC.
• The Sun's position is marked with this symbol: . At this location, the Sun will be at its zenith (directly overhead) in relation to an observer.
• The Moon's position is marked with this symbol: . At this location, the Moon will be at its zenith in relation to an observer. Note that the symbol is not showing the current phase of the Moon.
• Different shades of darkness are used to indicate night; these shades are in order from lightest to darkest:
  • Civil Twilight (lightest shade)
  • Nautical Twilight
  • Astronomical Twilight
  • Night, no twilight (darkest)
• Latitude circles
  • NPC – Northern Polar Circle, or Arctic Circle, is at latitude 66°34' N. At locations north of the Arctic Circle, the Sun is visible all day and night during a period before and after the June solstice.
  • NT – Northern Tropic, or Tropic of Cancer, is at latitude 23°26' N and is the northernmost latitude at which the Sun can be directly overhead (this occurs during June solstice, around June 21).
  • ST – Southern Tropic, or Tropic of Capricorn, is at latitude 23°26' S and is the southernmost latitude at which the Sun can be directly overhead (this occurs during December solstice, around December 21).
  • SPC – Southern Polar Circle, or Antarctic Circle, is at latitude 66°34' S. South of this latitude, the Sun is visible all day and night during summer in the Southern Hemisphere.
