During the last years some progress has been made in the determination of temperatures of central stars of planetary nebulae (CPN). The main reasons are the successful deployment of space crafts which made the more temperature sensitive spectral region in the UV accessible, and the application of NLTE-spectral analyses (e.g. Mendez et al., 1981). Therefore, a re-examination of the H.R.-diagram of CPN's seems to be in order.
