Abstract
Sgr A*, the enigmatic radio source located at the dynamical center of the Galaxy, is firmly detected in the frequency range of ~ 1 — few 102 GHz. For ~ 0.5 – 1 GHz and in the MIR range only significant upper limits of the flux density are known. Between ~ 1.5 and 600 GHz the time averaged flux density S υ is proportional to υ1/3 (υ: frequency). For frequencies higher than ~ 600 GHz as well as for those lower than ~ 1.5 GHz, S υ drops sharply.
