Pinhole camera exposure from 15 October - 26 December 2009 taken at the site of the ESO Very Large Telescope (VLT) - from the control room extension roof facing north. Note Unit Telescope 1 (Antu) just left of centre and the unbroken solar trails showing that it is never cloudy (!!!) on Paranal. Thanks to Gerd Hudepohl for placing the cameras and to Tarja Trygg for supplying the cameras and processing the results. Andreas Kaufer (observatory director) delivered and distributed the cameras.
