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.

Getauscht gegen Mittag auf Kaminstutzen;

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.
