The power specta for line intensities of several lines formed in the upper transition region around 100,000 to 250,000K are presented. A period of ~5 min. is clearly present in lines due to O III, O IV and O V. In one dataset a period approaching 10 min. is present for ~10 min. ... In all datasets examined, there is excess power below 1mHz everywhere along the slit, although the observed periods do not always come from the most intense regions. ... In all regions, the 5.0mHz power peak is smaller. ...
