Data Set Overview : At the ESO La Silla site is a direct imaging facility (DIFA) at the A Nasmyth focus of the NTT, in front of the image derotator which feeds the IRSPEC infrared spectrograph. Two remotely-controlled 45-degree mirrors can be inserted in the light beam to deviate the telescope beam either to a CCD camera (SUSI) or to an infrared array. In the configuration which has been implemented, SUSI is equipped with a Tektronix 1024**2 CCD with high quantum efficiency from the UV to the near infrared. The CCD pixel size corresponds to 0.13 arcsec in the focal plane of the NTT. A filter wheel and a shutter are located in front of the CCD. Processing : The authorship for the SUSI data is PI: Rita Schulz, CoIs: Therese Encrenaz, Joachim Steuwe, and Gunther Wiedemann. The images were taken during the impact week and show the disk of Jupiter through several filters. All the images have been bias subtracted and flatfielded. No other calibrations have been applied.

The scheduling of the observing programmes at the NTT can be adapted to the sky conditions. When the image size is better than 0.7 arcsec, the telescope can be configured for observing with SUSI. In order to take full advantage of this unique capability, ESO has now introduced a special category of observing programmes which require exceptional seeing and are executed in a service mode by ESO staff when the sky conditions are favourable.
