Right now

The most recent data we hold from NASA FIRMS (VIIRS) arrived 33 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

The satellite has seen heat at this spot on 116 earlier days since 13 February 2024, in 12 of the twelve months of the year. Heat that is there in every season usually comes from industry (a steelworks, a refinery flare, a gas field) or from routine burning, not from a wildfire. NASA's data do not say which.

20 satellite detections of this fire · 8 – 13 September 2026

A satellite sees a burning fire on each of its passes. This page gathers every detection of this fire; the address of each one leads here.

Recorded by satellite 53 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 10th strongest of the 28 detections recorded within 20 km of this point since 12 February 2024. The last comparable one was on 7 September 2026.

What the source measured

NASA FIRMS (VIIRS) reported 33 fire pixels with a combined fire radiative power of 62 MW, at nominal confidence, 2 km from Port Arthur.

The 33 pixels cover about 4.6 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.

Urban PEI: 103,233 within a heuristic 35 km radius; not unique people.

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.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Computed under scoring rules v4. Rows carrying other versions were judged by different rules and are not directly comparable.

Archived as “Critical” under the rule in force until 4 October 2026, which read the radiative power and the people nearby. A satellite sees heat, not an emergency: since then every detection is shown as low or medium; this one as “Low”.

Series begins 8 March 2026 for live collection; the monthly chart also counts backfilled detections from 10 February 2024. Collection gap: 14-26 August 2026.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.

Physical priority index · v4 (historical). Heuristic priority, not calibrated probability, predictive accuracy or damage. The legacy data-support index combines assigned source support and field availability. Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present.

Safety information

Heat shows up at this spot regularly, which usually means an industrial plant or routine burning rather than a wildfire. Nothing on this page is an alert. In a real emergency, follow local authorities.
