Abstract

The GEM (Galactic Emission Mapping) project is an international collaboration established with the aim of surveying the full sky at long wavelengths with a multi-frequency radio telescope. A total of 745 hours of observation at 408 MHz were completed from an Equatorial site in Colombia. The observations cover the celestial band 0h<α<24h, and −24° 22′<δ<+35° 37′. Preliminary results of this partial survey will be discussed. A review of the instrumental setup and a ∼10° resolution sky map at 408 MHz is presented.
