Where is the sun in the Lofoten Island? Ask your Prime

4909v108773Next week, we’re having our holidays in the Norwegian Lofoten Islands. These are located above the Polar circle, and therefore we can expect to have midnight sun (since next week is the summer solstice). Where can the sun be found next week in the Lofoten? it may happen that there are clouds for extended periods.

Precisely, Eddie Shore’s blog of this month is about this! He has written a program for the HP Prime about how to fin the Solar Position (Right Ascension, Declination, Altitude, Azimuth).

it uses as Input the following data:

  • Month
  • Date
  • Year
  • Local Time
  • Longitude
  • Latitude

A precision: the standard time must be used - daylight savings time not to be used.

You can find the program here:
