=================================================================== Tohban report: 2009-08-11 to 2009-08-17 Checked data from: 2009-08-09/00:00 UT to 2009-08-15/23:59 UT =================================================================== General Notes: ____________ 1. Apogee raise maneuvers for Artemis on B on August 10 at ~13 UT and C August 12 at ~11 UT 2. Approved implementation of timed bursts at 1330 UT for inner probes - yet to be loaded. 3. FGM Range will be set to mode 4 for the inner probes when they are between 3 and 5 Re. This is necessary to resolve sub nT field fluctuations in the inner magnetopshere (ICWs). It will become active firstly through ICCR_DOP093 on TH-A starting 2009-08-17. Data Collection Status: _______________________ Gaps in data: A: 14th August - 20-24 UT ESA - cause at this time unresolved 15th August - 22-24 UT All instruments - suspect memory saturation due to orbit phasing of FAST survey B: 10th August - 1300 - 1800 UT ESA - maneuvers C: 12th August - 1200 - 2400 UT ESA - maneuvers D: Full coverage E: 11th August - 23-11 UT All instruments except FGM - missed data dump pass see significant events below for details Science and region coverage: _____________________________ Inner probes are performing skimming passes of the dayside magnetopause. Fast survey collection is covering intervals through the magnetosheath and magnetopause with significant inner magnetosphere coverage. Burst data is being largely collected at the magnetopause with some bursts on density irregularities within the magnetosphere (see E 1300 UT Aug 15 for a radiation belt trigger). With the continuing maneuvers B is collecting observations primarily in the solar wind as is C. Significant Events: ____________________ Spurious: During a pass starting at 224-09:44, THEMIS D came up with an IDPU error caused by the ETC kicker kicking while compression was on (at ~224-00:52 UTC). The appropriate scripts were run during the pass to properly reconfigure the ETC and the error was cleared. ETC recovery was completed by ~224-09:56.
