Abstract
On the night of June 22, 2025, prior to the deep penetration bombing [1] of the Fordow Fuel Enrichment Plant located at 34.8845°N 50.9981°E [2], an infrared anomaly was detected by VIIRS approximately 3 kilometers north of the facility. This location is distinct from the enrichment plant itself. The anomaly was observed by two VIIRS satellites at 2025-06-21 22:57:18.789 UTC (two pixels) and 2025-06-21 23:23:40.796 UTC (four pixels). Using the VIIRS Nightfire algorithm [3], the detected heat sources were estimated to have a temperature of 1200 K and a radiative heat output of 2 MW.
