An abstract encoding of one day's measurements. Not a physical model and not an instrument feed.

20 August 2026 has no eligible record: density coverage below gate, density gap above limit, speed coverage below gate, speed gap above limit, temperature coverage below gate, temperature gap above limit. The portrait above remains the selected release.

Daily history

The 61 observed days ending at the selected day. Arrow through the cells; a hatched cell is a day without an eligible record and says why. Nothing is interpolated.

Position is the percentile of this day's mean among the eligible daily means of exactly the 30 or 60 preceding days. It describes position within that window, not rarity.

Encoding bounds: speed 334–599 km/s (linear), density 1.73–14.36 cm⁻³ (log), temperature 69,412–357,988 K (log). Values outside saturate the visual and are marked clipped; the number shown is unchanged.
