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.

Daily change and position
| Quantity | Change on previous day | Relative change | Prior-30 position | Prior-60 position |
|---|---|---|---|---|
| Speed | +60.58 km/s | +11.52% | — (fewer than 30 eligible prior days) | — (fewer than 60 eligible prior days) |
| Proton density | -10.48 cm⁻³ | -75.85% | — (fewer than 30 eligible prior days) | — (fewer than 60 eligible prior days) |
| Temperature | -157,471.52 K | -51.73% | — (fewer than 30 eligible prior days) | — (fewer than 60 eligible prior days) |
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.
