1 CIR Session Summary at Kennebunkport Marty Lee Durham, New Hampshire USA

2 CIR/SIR Survey (Lan Jian)

3 Stream Interfaces

4 GONG Plots

5 STEREO CIRs/SIRs Variations on Timescale of Days 25% of Events have Shock(s) Forward Shocks more Common than Reverse Shocks

6 CIR Geometry

7 Shocks at CIRs Shock Database (Kasper) Waves at Shocks (Blanco-Cano)

8 Waves at CIR Shocks (Blanco)

9 Corotating Ion Events Reames et al., 1997 Fisk and Lee, 1980

10 Energetic Particles Effect of Current Sheets (Bucik) Energetic Particle Variations (Dresing)

11 Energetic Particles (Dresing)

12 ratios wrt O for two cirs: left: CIR example showing spectral break, notice that the abundances not not change noticeably even though the intensities change by a factor of 10^8 over the range shown; right: CIR with just a steep spectrum, also see no significant changes over a smaller energy range. Compare with Cohen et al. 2005 JGR SEP event energy ranges; offset factors of 10 for various elements are same as in figure with plot of X/O vs Fe/C. INSET BOX: average of all 41 events for Fe/O, shows same small systematic rise from low to higher energies Ratios of heavy ion abundances show that spectral forms are virtually identical for species with a wide range if Q/M values intensities change by a factor of ~10^8 over range shown Mason et al., ApJ., 678, 1458, 2008

13 Geomagnetic Effects (Ian R.)
