Long-period comets comprise even more primitive material than short-period comets. Observations of their composition are diagnostic of the environment during their formation. There is a more than 50% chance that a bright long-period comet will be observable during the time of ISO observations. This comet should be observed by a similar program as comet P/Kopff in Guaranteed Time Observations. This program includes three observation sequences at three different heliocentric distances in order to observe the development of cometray activity and of coma composition. For estimation of the integration time it is assumed that this comet is as bright as comet P/Kopff.
