2025-09-28 — Didn’t process changes in NOAA solar wind reporting scale (essentially moving the decimal), which broke the model. Added a function to account for scaled values.
2025-09-27 — Made some major overhauls to the HF prediction formula. These should be much more accurate, though I know there are still some modifications required. Also made some minor legibility improvements to the graphics. 6m and higher are not calculated yet and should be ignored.
This index and the formulas used to calculate it are still in the early stages of development. Once I have received more feedback and have had real-world validation of its results, I’ll publish full details and make it generally available.
