Continue obsid 3964, a long HRC-S/LETG observation to measure metallicity in the narrow line Seyfert 1 galaxy Mkn 1044, coordinated with HST.

NOTES/ISSUES/PROBLEMS From the Solar Terrestrial Activity Report: "A huge, recurrent coronal hole (CH46) mainly in the southern hemisphere and with a large leading trans equatorial extension will rotate into a geoeffective position from late on June 24 until July 2." From the 9am status meeting: Three 34m supports. No issues. On-board loads good until 178:16:21. Ran CAP 820 to disable autonomous momentum unloading. JUN3003A products are out for a 2pm load review today. JUN3003 must be finalized today, since the on-line system will be down tomorrow for the transition to ONLS 3.9.3. If revised products are needed they will be issued and reviewed today. Radiation zone planning telecon at 3pm today, 405 244 5060 1165#. Promotion of the ONLS 3.9.3 will take place tomorrow, starting right after the 9am status meeting. Star working group tomorrow will review the heating in the ACA cavity due to the lowered focal plane temperature, and discuss how to proceed. Tomorrow's telecons: 11 am EDT, New eclipse handling plan. 405-244-5060, pin 1165# R. Giordano 3:30pm EDT, Review of the IRU-1 to IRU-2 process. 405-244-5060 1165# D.
