New and Misclassified Planetary Nebulae
1978
Symposium - International astronomical union
Since the "Catalogue of Galactic Planetary Nebulae" 226 new objects have been classified as planetary nebulae. They are summarized in Table 1 which gives the designations, names, coordinates and the references to the discovery. Further 9 new objects have been added to Table 1 and called 1proto-planetary nebulae1, but their status is still uncertain. Only 34 objects have been included in the present list of misclassified planetary nebulae (Table 2) although the number of doubtful cases is much larger.
