Satellite

Where the measurements are

Drawn server-side from the public event read model. Every mark is a measurement: nothing here is interpolated, smoothed or inferred.

-20°-10°0°10°50°60°1000 km

What each mark means

  • VIIRS (NASA)375 m

    No detections stored for this frame.

  • Meteosat (EUMETSAT)≈2 km

    Measures how much energy is radiated, which is what sizes the glow. Its individual pixel positions are not stored, so no Meteosat footprint is drawn — inferring one from the sharper layer would put a detection pixel on ground nobody measured.

  • True geographic scale, corrected for latitude. Frame is about 2703 km across.
  • At this scale both sensor footprints are smaller than a pixel, so no true-scale square is drawn. Two squares clamped to the same legible minimum would show a 1:1 ratio for a 5:1 fact.
  • The glow means “an event, roughly here”. Its area follows the measured power and its radius is capped, because an uncapped one would assert a burnt extent nobody measured. The number carries the magnitude.
  • Grey is what a later pass has superseded. Colour means the most recent sharp measurement, and it never fades with the clock — only newer knowledge demotes it.
  • A slate-blue glow is neither: heat one sensor saw and nothing has corroborated, or an event that has fallen outside recent coverage. It is not a confirmed measurement, and it is not an all-clear.
  • At country scale each event is one glow. Individual 375 m detections resolve on the event page, where they are larger than a pixel.

Measured activity

Current measurable activity

No events currently show measurable satellite activity.

Not confirmed

Unconfirmed heat, and events out of satellite coverage

These are neither measured activity nor an absence of it. Some carry thermal heat a single sensor saw and nothing has corroborated; others have fallen outside recent satellite coverage, so what is happening there is unknown rather than nothing. Each event says which.

No measurable activity

Tracked events without measurable activity in the latest observation

No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.
