Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 14 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
2 other detections within 20 km in the last 24 hours, the nearest 11 km from here.
Recorded by satellite today.
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 2nd strongest of the 10 detections recorded within 20 km of this point since 3 August 2026. The last comparable one was on 4 September 2026.
What the source measured
NASA FIRMS (VIIRS) reported 20 fire pixels with a combined fire radiative power of 199 MW, at nominal confidence, 14 km from Hornsby.
The 20 pixels cover about 2.8 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 979,883 people live within 35 km of this point.
Wind from W at 20 km/h at 19:00 UTC, according to MET Norway.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 53 out of 100, at 74 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Wind: MET Norway Locationforecast, CC BY 4.0.
Computed under scoring rules v4. Rows carrying other versions were judged by different rules and are not directly comparable.

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.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
