Observed wildfire event
Wildfire near Auvergne-Rhône-Alpes
Confirmed by a measured retrieval. No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.

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
Footprint at this scaleVIIRS (NASA) 375 m · not drawnMeteosat (EUMETSAT) ≈2 km · not drawn
- VIIRS (NASA)375 m6 hr ago
No detections stored for this frame.
- Meteosat (EUMETSAT)≈2 km26 min ago
Measures how much energy the fire radiates, 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 fire pixel on ground nobody measured.
- True geographic scale, corrected for latitude. Frame is about 48 km across.
- 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- Grey is what a later pass has superseded.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.
- Coastline, lakes and borders come from a generalised map with about 1,7 km between vertices, so treat every line as the shape of the geography and not as a surveyed boundary. It is drawn under the data and never over it.
- Place names sit at their own coordinates from an offline index of populated places. They say what is near the measurements — not that any named place is burning, and not how far the fire reaches.

MTG · VIIRS · Official
Verification ladder
- SeenObserved
A satellite observed a thermal anomaly here. Repetition belongs at this step: seeing the same thing many times separates noise from signal, but it does not separate heat from bright ground. Observed by: Meteosat (EUMETSAT).
- ConfirmedObserved
The anomaly carries measured energy or a 375 m position — the calibrated Meteosat fire product, or a VIIRS detection. Persistence alone never lights this step, because sunlit dry ground is persistent by nature.
- Quantified by VIIRSNot yet observed
VIIRS (NASA) passed overhead and measured radiated power at a 375 m footprint. Between passes it says nothing.
- Linked to an official sourceNot yet observed
An official update has been matched to this event. Official information outranks everything above it.

When each sensor looked
Meteosat looks every ten minutes; VIIRS passes a few times a day. The contrast is the point — between sharp passes there is no new sharp knowledge, only the ten-minute layer.
