The discovery of compact knots of highly processed material apparently ejected from the central star of the emission nebula Abell 30 is reported. This emission nebula possesses other unusual features. The extended emission region, about 2 arc min in diameter, has a very low surface brightness and exhibits a high degree of circular symmetry. The central star 05 fep, V = 14.3 is remarkable for its very high temperature of the order 200,000 K as indicated by the strong broad O VI, He II and C IV emission lines in its spectrum and the strong forbidden-line Ne V emission in the embedding nebulosity. Furthermore the star seems to be embedded in a resolved source of IR emission. These new observations emphasize the peculiar nature of A30 and its importance in studies of stellar evolution.
