A vertical column of dense white vapor rises prominently against a clear, light blue sky. The base of this massive plume originates from a partially visible industrial chimney, presenting as a light-colored, cylindrical structure with a flat, dark top, located in the lower-left quadrant behind the dark green foliage of a conifer tree. The branches of the conifer tree extend from the bottom left corner upwards and towards the center. A bare, dark deciduous tree branch is visible in the extreme lower right corner. The scene depicts an industrial emission, consistent with a thermal power plant, and is located at the TEC Sofia (Thermal Power Plant Sofia) in the Orlandovtsi district of Sofia, Bulgaria. No people or animals are present.
