=================================================================== Tohban report: 2009-03-31 to 2009-04-06 Produced at 10:00 on 2009-04-07 (at Berkeley by Jonathan Eastwood) Checked data from: 2009-03-29/00:00 UT to 2009-04-04/23:59 UT =================================================================== Summary: 1. Long shadows on Themis B and THEMIS C on Friday April 3 2009 - see instrument ops for details. 2. Be aware of daily shadow intervals on A, D and E 3. Summary plot issue described in previous tohban report has been resolved. 4. ICCRF_JSM083: Flight software on TH-D and TH-E to updated to version 5.2 5. ICCRF_JSM084: DBRAID grounded on TH-A, TH-D and TH-E 6. A discussion about probe-Sun attitude control was held by email this week: In Summary, the probes are tipped with respect to the Sun, so that the EFI sensors don't shadow during the tail and dayside seasons. They shadow during the flank seasons (hence distal braid grounding). The original and existing requirement is that the science North attitude (inner probes) is 8 degrees towards the sun on Feb 05 2008 06:30, which is around wedding day for the first tail season. However the orbits are precessing, so the apogee is at midnight local time in April 2010. Therefore the new requirement is that the science North attitude (inner probes) is 8 degrees towards the sun on May 1 2010 03:30, between summer 2009 - summer 2011. This change will be enacted after the 2009 dawn season, and applies to the inner probes. 7. During the upcoming maneuvers, tohban approved waiving the spin rate adjustment on TH-A (P5) on April 8th to relieve schedule pressure during the upcoming inner probe maneuvers. This means that the TH-A spin rate will not be optimized for ~10 days from April 8th. =================================================================== Science Target: 3/31: Themis AE = 200 at 4UT, all spacecraft in FS mode. =================================================================== ICCRs Approved: ICCRF_DOP084: This is to ground the EFI distal braid for the upcoming sensor shadow season (when in shadow photoelectron effects can otherwise contaminate ESA electron measurements) =================================================================== Data quality/collection status 2009-03-29/00:00 UT to 2009-04-04/23:59 UT: TH-A FGM: full coverage ESA: full coverage gap 18:45 -
