Although the Sloan Digital Sky Survey has permitted the discovery of an increasing number of new ZZ Ceti stars, recent published analyses have shown that there are still many relatively bright (V < 17) ZZ Ceti stars waiting to be found. We will discuss the discovery of several such objects in addition to a number of DA stars in which we detected no photometric variations. These were uncovered as part of an ongoing spectroscopic survey of DA white dwarfs from the McCook & Sion Catalog. By… CONTINUE READING
