2. THEMI GBO meeting 2 UCB 06/02/2003 Ground Based Observatories THEMIS GBO heritage IMAGE satellite FUV imager system; ROCSAT-2 ISUAL imager; NSF’s Automatic Geophysical Observatories ( All Sky Imagers in Antarctica) IMAGE FUV ISUAL PENGUIN-ASI

3. THEMI GBO meeting 3 UCB 06/02/2003 Each GBO has an all sky imager (ASI) and -as necessary- a ground magnetometer (GMAG). Sites have existing infrastructure (some have GMAGs). GBOs cover North American sector. GBOs satisfy L1 requirements of t-res ( 8GLT) with high margins (>2). Supplemented by existing Canadian & Alaskan magnetometers (denser coverage) and intl. networks (extended MLT coverage). 20 GBO sites in Canada and Alaska. 10 Education and Public Outreach ground magnetometers (EPO/GMAGs) in the US, under EPO program mngt. GBOs: A synoptic view of the aurora
