Extensive Swift X-ray monitoring of novae has revealed unexpected variability on the rise to X-ray maximum in all novae with extensive monitoring but the cause remains elusive. Only a long XMM exposure during this early variability phase allows RGS time evolution studies to fully investigate possible causes such as variations in absorption comma intrinsic brightness comma or temperature. We propose XMM time totalling 145ks for two triggered observationsdoublePoint a 100ks observation triggered during the early X-ray variability phase with <2d response and a second 45ks observation with >1week response time during the later SSS phase to find what has changed to make the variations stop. We will search both observations for transient short-period oscillations.
