We focus on the analysis of the unique highly variable observation and show that we might have observed a new class of variability. We then study the energetic dependence of a low frequency QPO from our steady observations.2 pages, 3 figures, proceeding of the IUC Colloqium 194, "Compact Bianries in the Galaxy and Beyond), Eds.
