Country overview
Thermal detections in West Wales and the Valleys
Events are grouped by what the satellites can and cannot currently say. A quiet observation is not a safety assessment, and an unconfirmed one is not an all-clear.

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.
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 475 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- Grey is what a later pass has superseded.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.
- 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.
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.
