1 A.Rees, T. Horbury and A. Balogh Ulysses Observations of Co-Rotating Interaction Regions.

2 Outline Group Talk (26 th Nov 2007) Ulysses Co-Rotating Interaction Regions Planar Magnetic Structures Technique Ulysses Results Simple Model Summary

3 The Ulysses Spacecraft Group Talk (26 th Nov 2007) Ulysses sits atop the Payload Assist Module-S (PAM-S) and Inertial Upper Stage (IUS) combination in the Vertical Processing Facility at the Kennedy Space Center. The Ulysses orbit from launch through Jupiter encounter and the first three orbits. Mission Day = 6261Heliolatitde = 75 o North Sun-Spacecraft Distance = 1.82AU

17 Idea (Bad?) : Group Talk (26 th Nov 2007)

18 Summary/Conclusion Surveyed Ulysses data for CIRs 1992/1993 CIR Season – 18 Events 1996/1997/1998 CIR Season – 22 Events Applied Planar Magnetic Structure Technique. Distinct heliolatitude trends in normal orientation. Simple plane model partially works.

19 Future Work Group Talk (26 th Nov 2007) Multi Spacecraft observations. WIND Spacecraft at L1 during 1996/1997/1888 Season Already surveyed WIND CIR events. Compare normal orientations given relative positions of Ulysses and Wind.
