Go through perigee passage, measuring cti on ingress and egress. Then do obsid 8911, an ACIS-S HETG observation of the high-mass colliding-wind binary system WR 140 to study shocks and plasma conditions as the system goes through periastron passage.

EPH temp: 106.37 degF EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last day. No issues. There will be a Project Interface Test at the next comm this morning to verify DSN software SPS D1.2. AUG2508A products should be out soon, for a review at 2pm today. A few thermal limit violations the past day, as we were in a forward sun position. TEPHIN went over 120 vs a prediction of 113. Model probably needs an update. DSops is catching up processing following last weeks Normal Sun Mode event.
