The lightmeter is installed on an approximately 50 cm high stone wall running around the roof of the COU and thus about 4m above the ground on the northern end of the COU main building.
The (dark) planetarium dome is about 20m to the S in its "closed" position and about 5m to the S in the opened position.
Some reflected light may be present due to the nearby white housings SQMs, at least during the COST campaign in May 2016.
The cielometer, a 1.5m high blue box is about 6m to the W. It should cast shadows on the lightmeter in the late afternoons a few days before the vernal equinox and after the autumn equinox.

The lightmeter is installed on an approximately 2m arm to avoid shadows and reflections from the rich instrumnentation on roof of the "environmental" container.
Maintenance visit during the COST-LoNNe inter-comparison campaign. Shielded USB-Ethernet extension cable installed after unstable USB-connection was diagnosed. The lightmeter is back up an running since 11:52 UTC on May 5th 2016.
