The 1m Zeiss telescope at ESA’s Optical Ground Station Station at Tenerife in Spain searched and followed Herschel and Planck. At the time the images were taken, Herschel, Planck and the Sylda support structure were travelling at an altitude of about 100 000 km from Earth.

Four bright objects are clearly visible in the images, three of them form a clear triplet moving in coordination in the centre (the Sylda is the fainter of the three). The fourth object standing is presumed to be the upper stage of the Ariane 5.
