  • Lots of bright stars here & there. It has become quite rough. Allowed myself an extra pouch (apples) to celebrate crossing the 0 degrees meridian.

What is a prime meridian, latitude and longitude?

A prime meridian is a meridian (a line of longitude) in a geographical coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its antimeridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides the sphere, e.g., the Earth, into two hemispheres. If one uses directions of East and West from a defined prime meridian, then they can be called Eastern Hemisphere and Western Hemisphere. (Source Wikipedia)

Latitude and longitude are a coordinate system by means of which the position or location of any place on Earth’s surface can be determined and described.

Latitude is a measurement on a globe or map of location north or south of the Equator. Technically, there are different kinds of latitude—geocentric, astronomical, and geographic (or geodetic)—but there are only minor differences between them. In most common references, geocentric latitude is implied. Given in degrees, minutes, and seconds, geocentric latitude is the arc subtended by an angle at Earth’s centre and measured in a north-south plane poleward from the Equator.

  • Each day I ration the amount of food I eat. I am really looking forward to my resupply after I’ve completed the 3rd circumnavigation. After which the rules allow me to take some supplies on.
  • I only use one burner of the stove, twice a day (breakfast & supper) because the stove plays up.
