HP-67/97 SOLAR CALCULATIONS

[plore90]

Hello everyone,
here I am again to publish my new solar calculation program. The program that is contained on two magnetic cards, allows you to calculate the position of the sun during the day in any location on earth identified by its geographic coordinates. The program calculates among the various parameters, the time of sunrise and sunset, the length of the day, the height in degrees at a certain local time and many other parameters. In the attached file, in addition to the program listed in pdf format, there is also a manual that explains how to use the program. As always, the program is written in the simplest way possible to make it quite understandable and therefore everyone can optimize it and expand it as they like. Obviously, it is necessary to have a basic knowledge of the meaning of the terms used in the program. See https://hal.science/hal-02175988/document
Thanks for your attention
