The Galactic Center is the closest galactic nucleus that can be studied with unprecedented angular
resolution and sensitivity. We summarize recent basic observational results on Sagittarius A*
and the conditions for star formation in the central stellar cluster. We cover results from the
radio, infrared, and X-ray domain and include results from simulation as well. From (sub-)mm
and near-infrared variability and near-infrared polarization data we find that the SgrA* system
(supermassive black hole spin, a potential temporary accretion disk and/or outflow) is well ordered
in its geometrical orientation and in its emission process that we assume to reflect the accretion
process onto the supermassive black hole (SMBH).
