Abstract
THE emergence of a displaced B-type absorption spectrum at the end of February, coupled with a drop in brightness to 3.5m–4.0m, suggests that, after a most unusual life-history of two months, the nova is now developing along more normal lines. Accompanying the O II and N II absorption lines—displaced with a velocity of about 900 km./sec.—there is to be seen an undisplaced bright band of [N II] at 5755.56. This can be traced back on the spectrograms to January 22.
