We present, for the first time, a new method to estimate seeing using remote sounding from the infrared night‐time data of the Geostationary Operational Environmental Satellite 12 . We discuss the correlation found between the ground‐based data and the satellite‐derived values from the analysis of the sites located at Cerro Paranal (Chile) and Roque de los Muchachos (Canary Islands, Spain). We obtain a ground–satellite correlation percentage of about 90 per cent. Finally, by studying the correlation between the data from the afternoon and the following night, we are able to provide a forecast for the photometric night quality.
