Doing obsid 4502, and ACIS-S/HETG observation of the close binary pre-main sequence (PMS) system, Hen 3-600, to obtain plasma diagnostics of two co-eval PMS stars.

Ephin temp 79.45 NOTES/ISSUES/PROBLEMS From the 9am status meeting: 3 supports no problems, on-board loads good until 80:13:15 MAR1904A products, which include a TOO observation, were distributed last night for a load review at 2pm today. Expect MAR2204A products later today for review tomorrow. Safemode simulation yesterday not able to get very far due to ASVT hardware problem. The CPE-A failed on ASVT, like an occurence last summer. At that time the West coast made a few minor repairs but did not find a root cause. Subsequently the ASVT CPE hardware units were swapped, and the CPE-B (in the -A slot) seems to be okay. Plan to repeat SIM next week. Meanwhile some procedure issues were found yesterday. A debrief will be held at 9:30 today in the conference room, and on 405 244 5060 1159# Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- no new quick looks. Long grating observation in progress. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
