\begin{abstract}
The MagPy software is a platform independent, multi-purpose software to assist geomagnetic data analysis primarily in observatory environments. It supports various common data formats of the geomagnetic community, among them instrument specific formats and general purpose formats like IAGA02, cdf and hdf5. Direct url-data access is also possible and new format conventions can be easily incorporated. Using the scriptable access of the underlying functions for import,  treatment, and export of data, an automated real-time analysis of geomagnetic data is possible. Currently supported are variometer data, scalar data and absolute measurements. For this, basic analysis features like filtering (gaussian, linear), smoothing and data fitting routines are available. Baseline stability tests, outlier detection and flagging procedures allow for a detailed examination of data quality. The package is completed by routines for coherence and spectral analysis as well as k-index calculation and variation (storm) detection making use of well established routines from the seismological community. Beside the scriptable access and command line routines, a graphical user interface based on Python WX is provided which allows, platform independent, windowed access to most routines and a direct graphical demonstration. The software has currently been tested on Linux and Windows systems.
