Thanks! This repo’s readme leads to gml.noaa.gov/grad/solcalc/calcdetails.html. This then references Astronomical Algorithms by Jean Meeus. That is available from the above linked archive.org page.
This is much closer to the real reason I was asking, as this little clock is intended as a primer for understanding object tracking for both astronomical observations and local rocket launches or transits.
















Call it Delilah-Cy in a prompt. It may yield interesting results depending on the model and how QKV alignment is setup. This is getting super deep into alignment thinking…
Unrelated: try telling a model, oh quit it, I know you never hallucinate. when it does something odd and watch the results.
