   Sonnenobservatorium Kanzelhöhe since 20.8.2009        

The original sensor was the number L19 of the original International Year of Astronomy 2009, prototype series. It recorded from August 2009 to June 2017. The new sensor is a Mark 2.3l, recording since 2019-04-18 12:00 UTC.

To get more distance from the Aeronet and a french experiment, the position was moved about 2m to the SW end of the platform, just south of the total radiation multiple radiometers, and 1,5 m W of the star-pyrrheliometer.
