Abstract. I have collected all the WET archival data on the pulsating DB white dwarf stars (DBVs) and re-reduced them. In addition, the WET has recently observed three DBVs. Preliminary results on PG1115+158, PG1351+489, KUV05134+2605, PG1654+160 and PG1456+103 are presented, and the future of the data is outlined.

Key words: stars: white dwarfs, oszillations, individual: PG1115+158, PG1351+489, KUV05134+2605, PG1654+160, PG1456+103
