We present a new local interstellar spectrum for cosmic ray electrons over an energy range from 1 MeV to 70 GeV .
Below ( 0.8 \pm 0.2 ) GeV it has a power law form , E ^ { - ( 1.55 \pm 0.05 ) } , with E kinetic energy , which is consistent with previous studies .
This is derived from comparing Voyager 1 electron data observed during 2010 with a comprehensive modulation model .
However , reproducing the PAMELA electron spectrum observed at Earth during late 2006 and to address an unexpected increase in the electron spectrum between \sim 2 GeV and up to \sim 20 GeV , a spectral index of - ( 3.3 \pm 0.1 ) instead of the reported - ( 3.18 \pm 0.05 ) was found for this energy range .
This feature can not be caused by solar modulation or any other process inside the heliosphere .
