Our Nov2018/Mar2019 SXD measurements verified a huge increase in HeI and FeII lines since 2006/2007, with new bifurcated line profiles indicative of strong jet outflow, consistent with the presence of large amounts of newly accreting material from the purported Chandra 'planet-eating event' of 2014-2016. On 28Sept2019 we observed the system for the first time in its faint optical state, and found a marked flaring/breathing change of the CTTS's accretion disk. By 02Feb2021 it had mostly relaxed. It is critical that we continue to monitor this developing solar system's behavior. PROGRAM_ABSTRACT_END
