Launched on the 11th of June 2008 , the Fermi Large Area Telescope ( LAT ) has made several outstanding scientific contributions to the high energy astrophysics community .
One of these contributions was the high statistics measurement of the Galactic Cosmic Ray ( GCR ) electron + positron spectrum from 20 GeV to 1 TeV .
The Fermi satellite is in a nearly circular orbit with an inclination of 25.6 degrees at an altitude of 565 km .
Given this orbit it is possible to measure the GCR electrons + positrons down to roughly 5 GeV .
However , this lower limit in energy is highly dependent on the orbital position of the LAT in geomagnetic coordinates due to the rigidity cutoff .
In order to measure the spectrum down to these energies it is necessary to sample the population of electrons + positrons in several different geomagnetic positions .
In this poster we present the analysis performed to extend the lower limit in energy of the GCR electron + positron spectrum measured by the Fermi LAT .
