By abrasion Leif, geesh never thought of that. Thanks for the tip Leif. I’ll work on it.
Did notice that you havn’t responded yet with the usual “we already knew that,” on that power point of Stefan Eriksson’s entitled:
Ionospheric convection response to high-latitude reconnection and electrodynamics of a split-transpolar aurora (University of Leicester, 2006) [.ppt]

One thing though, if you didn’t already know this, do man up and say so.
One other thing you can not ever ask is me to ah.. man up. Only thing I can find is one part of my brain that may at times have some semblance.

Eriksson is investigating the high-latitude response to reconnection. This is an effect that I discovered in 1968. Google: Svalgaard-Mansurov Effect

Hmm already knew about dual polar arcs. One polar arc flowing one way and another polar arc flowing the other way? And you didn’t mention this before??? lol

1. Introduction
..[2] Single and multiple auroral arcs are often observed at
very high latitudes during northward interplanetary magnetic
field (IMF) conditions [Lassen and Danielsen, 1978;
Burke et al., 1982; Carlson et al., 1988; Valladares et al.,
1994]. Such arcs are generally aligned in the Sun-Earth
direction and they are typically caused by precipitating
electrons with <2 keV average energy. In the literature they
are referred to as Sun-aligned arcs, polar cap arcs, transpolar
arcs (TPA), or theta aurora. Burch et al. [1979] first reported
that polar arcs occur at flow shears where the corresponding
dawn-dusk convective electric field points toward the center
of the electron acceleration region. Subsequent reports have
confirmed that the arcs typically coincide with a localized
upward field-aligned current (FAC) sheet at a flow shear
with a converging electric field [Burke et al., 1982; Carlson
et al., 1988; Obara et al., 1993; Carlson and Cowley, 2005].
..[21] The split-TPA feature also appears to be consistent
with the physics contained in the Zhu et al. [1993] M-I
coupling model of multiple polar arcs. However, the main
difference between this model and the 14 February 2003
split-TPA event is related to the initial state and the
subsequent evolution of the dual-arc system. The split-
TPA and the mesoscale structure observed by DMSP F13
evolved as a bifurcation of a preexisting large-scale TPA
[see also Craven et al., 1991] and the transverse width of
the split-TPA was comparable to the width of the original
TPA. The Zhu et al. [1993] model, however, gradually
evolves from one mesoscale primary arc into multiple arcs
distributed over an increasingly wider region until a steady
state width is achieved. In summary, although a local
Pedersen current closure requirement probably determines
the width of the intermediate downward current region, we
still need to understand what initiates the development of a
downward current at the center of the primary TPA in the
first place if we assume that the TPA coincided with an
initial large-scale upward FAC."""

Maybe you can help them out here. Read the last line from the above pdf. Man o Man an existing auroral arc splits into two with different rotation. oops sorry just filing away. Like what is the effect of the polar vortex when the split occurs. What is the effect on the earth system period. Must have gotten up on the wrong side of the bed.
Just the facts what do you got on gravitational fields and magnetic forcing? Just think out loud again.
