SyzygyAn atlas of California’s sky.

One control, both directions of travel. The Sun, the Moon and the galactic centre are recomputed from arithmetic as you drag — no request goes anywhere — by the same engine that reconstructed every photograph in this archive. Which is why the past and the future look the same here: the engine cannot tell them apart.

Oat Mountain, night of 15 August 2026. Times are mean solar time at that place.

Computed when this page was built by the same engine that reconstructed the archive — from the published area, meaning a centroid rounded to about 1.1 km and the middle of this place’s elevation band. No exact coordinate is involved, and no request leaves this page. A photograph’s own page carries the values computed from where it was actually taken; they agree with these to the 0.1° both are shown at.
