J. Abstract We report on spectroscopic observations of the AGN galaxy Mrk 372. 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 Hβ the broad line component disappeared leaving only a very weak, narrow line. Observations near Hα, however, do reveal the presence of a broad component.
