摘要：
We briefly describe the analysis of single-site data collected from 1982 to 1992 for the pulsating DB white dwarf GD 358. We show that the amplitudes of almost all of the l = 1. modes change over time, and some of the l = I modes disappear for months at a time. We also find a new mode at k = 19, with a frequency of similar to1173 muHz.
