IR observations of the region within 0°.5 of Sgr A are discussed. The total IR luminosity is 150 × 106 L⊙. Most of it is stellar radiation, absorbed by low temperature dust and reradiated in the IR. There is no unique interpretation for the highly structured infrared core. It may comprise compact infrared sources like those in some Hn regions, or the structure may simply result from the dust distribution. Nonthermal radiation is also feasible, but a tradeoff between source luminosity and extinction is possible and prevents a final decision on this question.
