In this paper, we present results of an intensive search for periodic variations in the strength of the Hell emission line of �2 Vel relative to the nearby continuum. The data were obtained in 1986 and 1988 using an automated optical system located at the Amundsen-Scott South Pole Station. Ten of the data sets have a time resolution between 2 and 3 minutes and consist of 2.3 - 20.4 hours of continuous photometry (Taylor, AJ, in press). Three of the data sets have a time resolution of about 1 minute and span between 1.2 and 6.5 hours.
