How long did the Vesele fire last?

According to the heat detections seen by satellite, it burned from 19 September 2026 to 20 September 2026 (2 days between the first and the last detection). There is no perimeter yet to date it.

How much area did it burn?

There is no official perimeter yet. Heat detections rebuild about 168 hectares with fire (1.7 km²); Copernicus will publish the measured figure within days.

What was the weather like?

During the fire the temperature reached 28.2 °C, humidity dropped to 26 % and gusts hit 19 km/h. The fire danger index (FWI) reached 19, class Moderate.

Where does this data come from?

From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ukraine (geoBoundaries). It is not an official report.

Vesele fire, 19 September 2026 Веселівський район · Ukraine

Out · last detection 20 Sept 2026, 11:30 UTC

Satellites first detected fire on 19 September 2026 in Vesele, Ukraine. It has been active for 2 days, with 9 heat detections and an area with fire of about 168 hectares rebuilt from them, spread across a single municipality.

Copernicus has not yet published the burnt perimeter, which takes a few days to measure on satellite imagery. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from

The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
