What the satellites saw
Every pixel VIIRS returned inside 11 km of this fire: 42 in daylight, 38 on the night pass. A pixel is 375 m, so the squares are drawn at the size the measurement has.
Where
Coastline and borders from Natural Earth at 110 m — regional context, not a survey. Each layer above is its own address, so a view can be shared.
A fire was first detected here at 03:49 UTC on 11 October 2026, 38 km NNW of Muquém do São Francisco in Bahia, Brazil. At its most recent pass it was putting out 1,076 megawatts of radiative power across 80 separate satellite detections.
The detections span about 7.2 km of ground.
No settlement in our index has population recorded within 25 km.
When the satellite first saw it
In local solar time the first detection falls at 00:54, which is the dead of night. VIIRS passes about 01:30 and 13:30 local solar, so this is when the satellite looked: the fire began somewhere in the twelve hours before.
It was seen across 23.7 hours of satellite passes.
47% of the detections came from the night pass.
What this ground has done before
This ground has burned before. Our archive records fire here in 2013, 2021, 2023, 2024, 2026, across 16 days, most recently on 2026-10-10.
Wind and weather
At the fire, wind was 15 km/h from the ENE, carrying smoke and embers towards the WSW. Temperature 29°C, relative humidity 34%.
Twelve hours on, the forecast has wind at 12 km/h from the ESE. These are model figures at roughly 10 km resolution, not a reading taken at the fire.
How it compares
By radiative power this is the 148th largest fire burning anywhere on Earth in the current window.
Where analysis would go
Our screening pass scores this fire 0.90. The score ranks where analysis is worth spending.
What the screen noticed: 62 distinct events in one space-time group; activity compressed 7x versus a week-long release; 55% of events first seen at night (local solar), when machinery is not working; events spread over 26 km - too far apart to be one fire, close enough to share an actor; 10 detections per event - large spreading fires, not many ignitions.
Read from satellite detections and weather. No roads, no land cover, no ground visit.
What else this page knows
Each of these is attached to every fire, including this one.
A detection is a heat signature at 375 m, about three hours behind the satellite. Cloud, smoke and canopy hide fires; each satellite passes twice a day. Not for evacuation or life-safety decisions — follow your local fire service.
