The Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA-20 platform observed wildfires just west of the Yenisei River in the Krasnoyarsk region of Siberia on June 17, 2026. In the false-color corrected reflectance image above (bands M11-I2-I1), the wildfires appear as patches of dark red (burn scars) ringed in bright red, which marks the active fire front. In this band combination, smoke appears light blue/teal.
Press the "play" button in the lower left corner of the second map to view the growth and progression of the fires from June 12 to 17. The false-color image is overlaid with the thermal anomalies layer, in which each of the red dots represents a fire burning within a 375m pixel. The fires grew from roughly 16,700 hectares (41,300 acres) on June 13 to 62,600 hectares (154,700 acres) by the morning of June 17. The rapid spread of the fires has been attributed by local authorities to high temperatures and an abundance of dead trees due to severe Siberian silkworm infestations.
