At 09.33.34z a reconfiguration of one of the electrodes of ASH1 took place;
A synchronisation problem arose on FEEU1 at 033.09.33.34.727z (EvID 17), this triggered an anomaly event related to ASH1 which brought to the electrode reconfiguration.
Following this autonomous EGG recovery the electrodes combination matrices have been changed (EvID 32) and consequently the thresholds for the health detection and for the saturation test were changed (EvID 38 and 39).
Consequently to this the Science Dynamic Conditions were lost at 033.09.33.35.498z; the Science Dynamic Conditions were regained at 033.11.03.35.995z.
