THIS PROPOSAL WILL PROBE THE COSMOLOGICAL DIPOLE OF THE EXTRAGALACTIC GAMMA-RAY BACKGROUND (EGB). THE EGB DIPOLE DUE TO THE LOCAL PECULIAR MOTION APPEARS MEASURABLE FROM THE 12 YR FERMI-LAT DATA AND SHOULD PROVIDE IMPORTANT VERIFICATION OF THE KINEMATIC ORIGIN OF THE DIPOLE OF THE COSMIC MICROWAVE BACKGROUND. THE PILOT STUDY SHOWS THAT WITH ASSEMBLING THE FULL MULTI-YEAR DIFFUSE MAPS FROM LAT DATA OVER ~[0.1-10] GEV WE CAN IDENTIFY THE EGB DIPOLE AT SIGNIFICANT S/N AFTER ACCOUNTING FOR GALACTIC GAMMA-RAY EMISSIONS AND SYSTEMATICS.
