A new facility for precision measurements at ultra-low magnetic fields has been built in the new physics department building and is currently under commissioning. With a noise damping performance of order 10^5 below 1 Hz and background stability at the pT level over a day, the environment is among the few top facilities world-wide. A series of first experiments has been performed to investigate the possibilities for new or improved measurements. I will discuss an overview of the facility, and first measurements of spin precession of hyper polarized noble gases, SQUIDs and atomic magnetometer noise floor measurements, as well first space- and time-resolved magnetic signals of human hearts and brain activity. Also, an outlook of planned activities will be given.
