  We present for the first time a new method to estimate the seeing using
remote sounding from the IR night time data of the GOES 12 satellite. We
discuss the derived correlation between the ground 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 get a ground-satellite
correlation percentage of about 90%. Finally, studying the correlation between
the afternoon data and the following night, we are able to provide a forecast
of the photometric night quality.
