This licence has been issued for the scientific research application No.4868.
Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground, and these patterns project out into space along the Earth's magnetic field lines.
The radar installation...

Résumé:
The research team want to test several prototype instruments: cameras, radio receivers and an X-ray instrument on a high-altitude balloon. The hope is to collect data from all of those instruments that will help to understand the high-energy particles involved in pulsating aurora.
The research team will observe pulsating aurora through the prototype cameras and anticipate deploying on a frozen ...

Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground and these patterns project out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications.

Résumé:
Using passive, electromagnetic instrumentation designed and developed for use on the ocean bottom, we will make measurements of the time-varying electromagnet fields caused by the northern lights at 10 lakes, 3 in Nunavut, in the Slave craton. At each lake an instrument will be deployed from a Turbo Beaver float plane and the instrument will drop to the bottom of the lake and start to make recordi...

Résumé:
The observations will be made by an all-sky TV camera. The camera is computer controlled and should only require minimal attendance. The camera will record the auroras over Fort Smith with 1 minute resolution, storing the images on coputer disk and transferring them to the Internet. Hoping to use the Upper Air Station as this facility would be ideal for optical observations....

1994 Résumé:
Beams of barium and calcium ions, from a rocket launched from Poker Flats, Alaska, will be released into the aurora. These beams will be observed using two low-light-level TV systems set up outside the Upper Air Station in Fort Smith. Each system will be filtered for barium ion light and calcium ion light respectively. The data will be recorded on video tape. The experiment will take place nea...

19931992 Résumé:
In previous years, instruments were installed in Clyde River, Igloolik, Pelly Bay, Gjoa Haven, Pangnirtung, Coral Harbour, Repulse Bay, Cape Dorset and Iqaluit in order to measure the earth's magnetic field. Data will be collected continuously by these instruments, called magnetometers, for a period of several years. This information will help us to understand the nature of the aurora borealis....

Résumé:
Two GPS satellite receivers will be stationed at the Yellowknife Airport in a roving land vehicle. Solutions will be made to the vehicle's position to determine whether the signals have been adversely affected....

1991 Résumé:
The Norman Wells Observatory has demonstrated to be a very good site to place a remote aurora monitoring observatory to support a scientific experiment called SPIRIT II. For this project, the researchers will continue to investigate the aurora's strength and position, magnetic disturbances etc. The observatory at Norman Wells fills a gap in the internationally collected and shared auroral data se...
