Don't know whether this is related specifically, though I think it *may* be? Assuming we're talking about excess / anomalous energetic electrons... Apologies if this paper has been mentioned already. Haven't had time to peruse the 4 pages of the thread yet.

This brief note speculates that the recently reported residual CMB signal [Seiffert et al 2009] may originate within the Sun’s heliosheath. A temperature spectrum function is derived that has the same power law form as the fitted function in Seiffert et al. In particular a spectral index of +2 is implied. An optically thin radiating shell of thickness ~ 1AU could match the required 1K deg power law amplitude. A possible mechanism for the heliosheath magnetic fields is discussed based on Alfven’s heliospheric current model with embedded double layers as the energy source for the relativistic electrons.

If it's not directly related to the original thread's topical article(s), is it at least potentially applicable to the same issue?
Is it possible that our solar system (or rather the heliospheric boundary / heliosheath) *is* the source of some of the cosmic rays being detected by ATIC and/or Arcade 2 as suggested (lightly) by Sharpe?
Anyway, thought folks would find the article of interest re: the current topic. Discuss amongst yourselves.
