Scientific paper

Photometry through various apertures was performed both on the nuclear region and at selected points in the coma, using standard IHW cometary filters. Only a preliminary analysis of some of the data has been performed. During both observing runs the apparent magnitude of the nucleus showed significant changes from night to night. CO+ and H2O+ ions were detected close to the nucleus in May. Measurements at various radial distances from the central condensation of the OH 0-0 band emission were analysed, to yield a parent production rate at that time.
