Ground-Based
Observatories (GBOs)

  • All the magnetometers and all-sky cameras have been built and tested.
  • 14 of 20 GBO sites have been deployed. All of them, except one, are operating normally.
  • All the E/PO Magnetometers have been installed.
  • UCLA is working to produce a website where one can access the mag data as ASCII files. If you want to see THEMIS Real Time images of aurora around Canada and Alaska, go to this URL:
