Shift L1397. Start at 139:13:00 GMT = 08:00am 19 May EDT End 10:00am 19 May SOT Lead DAS (Times will be given in GMT on day 139.) PLAN ---- Continue running load MAY1903B. Doing CTI measurement prior to perigee passage. Upon egress will do obsid 4027, continuing HRC-S/LETG observations to study the AGN outflow seen as an ionized absorber in the bright Seyfert 1 galaxy Mrk 279.

NOTES/ISSUES/PROBLEMS As of May 12, the LETG/OUT angle has started reading 77.59 instead of 77.96. From the 9am status meeting: Seven supports over the weekend. No issues, all dumps current. Two load segments were uplinked, on-board loads good until 143:03:39. MAY2603 products expected out today for a review tomorrow. Gyro current has been slightly noisy the past couple of days. Mean level the past day has been about 144 and not very noisy. Expect a presentation package on the MUPS to be issued mid-week this week, for a review telecon the following week (i.e. week starting Tuesday, May 26, after the memorial day holiday). Planning an IRU presentation package out late Tuesday, for a Project review telecon 1-3pm on Thursday (time tentative, to be scheduled).
