Variability of the broad line spectrum of Markarian 372


Spectroscopic observations of the AGN galaxy Mrk 372 are reported. In 1986 the spectrum was that of a Seyfert type 1.5 with very broad permitted lines and modestly broadened forbidden lines. In 1990 the spectrum is that of a Seyfert type 1.9. At H-beta, the broad line component disappeared leaving only a very weak, narrow line. Observations near H-alpha, however, do reveal the presence of a broad component.
