Received 15 December 1988




The RR Lyrae variable AF Scuti was examined for period changes in the interval 1917 through 1988 on the plates of the Maria Mitchelll Observatory collection. The deviation from a constant period was found to be statistically significant and the data indicate that the period is increasing at a rate of 0.072 day per million years.
