New UBV observations of the classical Algol system AW Peg were present
ed. The photometric minima times were collected and used together with
the new determinations in a period study. No sign of any period chang
e was found from observations covering more than sixty years. The B an
d V light curves are analyzed by means of the Wilson-Devinney approach
. It was verified that the system is semi-detached with a Roche lobe f
illing secondary.
