On 23 June 2009 the PACS integral field spectrometer recorded its first spectra during the in-orbit commissioning phase of the Herschel mission. These observations, made before fine-tuning or in-orbit final calibration was performed, demonstrate the excellent condition of the spectrometer even before the Performance Verification Phase begins. The target object was NGC 6543, also known as the Cat's Eye Nebula.
