Optical Mesosphere Thermosphere Imagers (OMTIs)
Auroral Data from Canadian Stations

Solar-Terrestrial Enviroment Laboratory, Nagoya University

This homepage is to view optical and magnetic field data from two Canadian stations (Athabasca and Resolute Bay), operated by the Solar-Terrestrial Environment Laboratory, Nagoya University.

Please note that the data are just for browsing purpose and are not fully calibrated. For digital data request, please contact K. Shiokawa .

Here are some notes.

The observations are carried out in collaboration with the following institutions.  
    Resolute Bay (RSB): SRI International, USA, 
                        University of Calgary, Canada
                        University of Electro-Communications, Japan 
    Athabasca (ATH): Athabasca University and University of Calgary, Canada

This observation at two OMTI stations in Canada is mainly carried out by the Division II members (K. Shiokawa, Y. Otsuka, and T. Ogawa) of the Solar-Terrestrial Environment Laboratory (STELAB), Nagoya University. We thank Y. Katoh, M. Satoh, and T. Katoh of the Solar-Terrestrial Environment Laboratory, Nagoya University, for their helpful support of the development and operation of the instruments. K. Hosokawa of the University of Electro-Communications provides various data plots of the all-sky imager at Resolute Bay. A. Ieda of STELAB produces the keograms of the imager at Athabasca.

The observation at Resolute Bay is carried out in collaboration with the SRI International, USA., the University of Calgary, Canada, and the University of Electro-Communications, Japan. The observation at Athabasca is carried out in collaboration with the Athabasca University and the University of Calgary.

This work is supported by Grant-in-Aid for Scientific Research (16403007) and by the 21th Century COE Program (Dynamics of the Sun-Earth-Life Interactive System, No. G-4) of the Ministry of Education, Culture, Sports, Science and Technology of Japan. This work is also supported by the Project 2 (Initiatives in geospace research using coordinated ground-satellite experiments) of the Geospace Research Center, Solar-Terrestrial Environment Laboratory, Nagoya University.
