During the last week Chandra completed the observing schedule as planned. Chandra passed through the eighth (final) eclipse of the season on Jun 14, with nominal power and thermal performance. Realtime procedures were executed on Jun 14 to disable SCS-29 and to dump and clear the EPS glitch counters as post-eclipse season actions. Additional real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load. Chandra press and image releases were issued on Jun 18 featuring Chandra observations of a young protostar referred to as HOPS 383. This object, about 1,400 light years from us, is thought to be similar to our Solar System in its earliest stages. A strong X-ray flare lasting over 3 hours detected in a 2017 Chandra observation provides evidence of magnetic activity in the earliest stages of formation of sunlike stars and suggests a mechanism to drive an outflow that removes angular momentum from the system and allows material from the surrounding disk to fall onto the growing protostar.
