Recorded by satellite 19 days ago.
A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.
It is the 3rd strongest of the 37 detections recorded within 20 km of this point since 15 March 2026. The last comparable one was on 7 August 2026. 2 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 13 fire pixels with a combined fire radiative power of 145 MW, at high confidence, 10 km from Vovchansk.
The 13 pixels cover about 1.8 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.
FIRMS does not report burned area, and neither do we.
An estimated 30,415 people live within 20 km of this point.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 39 out of 100, at 74 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.

Safety Information
If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.
