  14. Questions Related to March 5, 2008 0600+ event Establish (magnetospheric) topological location of onset arc. Establish (magnetospheric) geographical location of arc. Have (resolve?) the t=0 debate (is “onset” meaningful in all events?). Can we relate waves in aurora to waves in current sheet? Why does the outer CPS aurora brighten before onset? Why is the arc that brightens a new arc? What can we infer from the fact that the arc is so L-shell aligned? Why is the dipolarization at TH-C and GOES 11 so much later? What controls the azimuthal evolution of the breakup? What is the magnetotail instability? Is this CD or NENL? [is that meaningful in the these cases]? SOC and turbulence – can we establish from TH-D/E that the L~11 magnetosphere is in a critical state in the late growth phase? Why is the injection “spiky” in this event (like February 26)?
