Abstract
Magnitude observations of the nova are published in Nos. 4566–67 of the Astronomische Nachrichten and Dr. Rosenberg describes his observations of the spectrum at the Tübingen Observatory. On March 19 a red-sensitive plate snowed well-marked radiations corresponding to Hα, Hβ, and Hγ. Their breadth was about 30 A.U., of which 9 A.U. was shifted towards the red, and 21 A.U. towards the violet from the normal positions. Hy presented three maxima at λλ4348, 4339, and 4332 respectively, and an examination of the spectrum for polarisation effects gave a negative result.
