magnetometers used for searching for beyond the standard model spin interactions. It presently
consists of 12 active magnetometer stations spread around the globe with gps-time stamped data being
continuously streamed to a central server for analysis. Of special interest is the search for dark matter in
the form of interactions with axion - like particles (ALPs) which may form ALP domain walls and ALP
stars. Such interactions will have the signature of temporally coincident transients occurring in multiple
sensors in the network. I will in this talk describe the experimental details of the network and review some
data analysis ideas.
