 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Dear Members, Has anyone done a program to convert Local Time to UTC , Atomic Time , Sidereal Time. Look I know there are APP’s for this but the fun of programming it. Regards, RicM |

This led to a fun little excursion. Me being too lazy to download the files one by one, so I opted for my old friend "wget.exe". It probably would have been quicker to download them individually, but I got to play with a bit of regex and sleuthing around the web page source to get the proper links to the files. But in case anyone is interested, I've included the files in "Sky & Telescope.zip" Sky & Telescope BASIC Files.zip Disclaimer: These are a copy of the files kindly provided by Sky & Telescope, and are provided as-is. |

I would highly recommend DownThemAll extension on Firefox / Mozila to get all the files with one click. https://www.downthemall.org/ https://celestrak.org/software/satellite/sat-trak.php Has a huge collection of software relating to earth satellites. I am going to revive a line-number remover with label creation that will accept a serial .bas file input and create a serial output file. Edited 2024-01-30 02:21 by barewires |

Good to know! I don't use Firefox, but I'm sure that it is available for other browsers. I thought about looking for an easier option, but wget and I have a long history. :) |

RicM, Attached are my MMBASIC astronomical routines (from Jean Meeus' Astronomical Algorithms) that will have some of the routines you were after. There is a pdf in the zip folder that explains the routines. The astronomical routines are in an include file (MMB_Astro.inc) with a BASIC test file (AstroTest.bas ). The test file compares my routine outputs to the US Naval observatory MICA2 program. This creates a text file of the errors, but note if running this on Windows you may need to change line 160 of AstroTest.bas to the folder you want the output text file to be saved in. It’s been some time since I played with these but the test program should work out of the box on the Windows version of MMBASIC, but note the include file is quite large. Hope you can extract what you need from this. Gerry MyZip.zip |
