A spectrum of comet Hale-Bopp

shows such a spectrum, after it has been subjected to preliminary image processing. It is based on a Hale-Bopp spectrum, obtained in the morning of September 5, 1995, by visiting astronomer Birgitta Nordström (Copenhagen University Observatory, Denmark) with a CCD on the Boller & Chivens spectrograph at the ESO 1.5-metre telescope at La Silla. The exposure lasted 30 minutes and the slit was placed in the East-West direction. Hector Vega (ESO) assisted during this observation.
