5. Conclusion

We present the first individual distance determination of the PN around Sakurai's Object using the extinction method. The reddening vs. distance relation established using stars in a very small field is in full agreement with galactic structure. The value of 1.1 kpc obtained results in an absolute magnitude of MV = -0 [FORMULA] 4 to -1 [FORMULA] 5. For the old PN we find a diameter of 0.17 pc and a kinematic age of about 4200 years. This comparatively small distance is compatible with all available data, while much larger distances lead to discrepancies. We are confident that a reliable distance value will help us to gain new insights in the very late He-flash phenomenon which is taking place right before our eyes.
