Sakurai's object (V4334 Sgr) in all likelihood is a star undergoing a final helium flash. Since its discovery in 1996 observers have been trying to keep up a monitoring of the amazingly fast changes of its stellar properties; changes occuring on time scales of a few weeks or months. By enabling us to follow the evolution of one object in `real time' it relieves us of the need to painstakingly assemble a consistent understanding from different objects, at the various stages of evolution that they have reached from differing starting conditions. Sakurai's object thereby offers a unique opportunity to study an important but short-lived aspect of regular stellar evolution, the final helium flash.
