AUTUMN (Athabasca University THEMIS UCLA Magnetometer Network) was emplaced in 2005, originally as a subauroral network in the province of Alberta. With the help of the University of Saskatchewan and Berkeley, a magnetometer at Inuvik, NWT was added in 2006. A magnetometer was installed at Fort Vermilion, Alberta in 2007, and the AUTUMN Edmonton magnetometer was moved to La Ronge, Saskatchewan in 2008. AUTUMN thus now has several auroral zone stations. The STEP (Solar-Terrestrial Environment Program) chain originated in the 1980s. Several of its stations are still operating, some with both fluxgates and induction coils. Many have been upgraded to use the internet, and all now feature GPS timing and 1s cadence (fluxgates). In 2007, a cooperative approach between NRCan, universities, and the POLARIS infrastructure for Earth Science project brought about magnetometers on the east coast of Hudson Bay (EHB), with good spacing and placement in the auroral and subauroral zones. We will describe how the above research magnetometers complement the observatory instruments of the NRCan CANMOS array to facilitate space physics investigations on a continental scale. We also describe the challenges facing a large magnetometer array composed of diverse instruments, and run with little funding. AUTUMN's latest stratagem for wide magnetometer deployment with minimal effort or cost has been the development of the $500 netPICOmag, described elsewhere. Finally, we describe how to obtain data, and give examples of studies done using it.
