Canada has three zones of geomagnetic activity: the polar cap; the auroral zone; and the subauroral zone.
Canada has three zones of geomagnetic activity: the polar cap zone, the auroral zone, and the sub-auroral zone.
This area is known as the Auroral Zone or the Auroral Oval.
Geomagnetic activity is derived from measurements made at magnetic observatories located in the polar cap, auroral, and sub-auroral zones.
Geomagnetic activity is especially strong in the surrounding auroral zones.
For each of the three major zones (subauroral, auroral, polar cap), the range of activity is divided into four classifications: quiet, unsettled, active, storm.
During ageomagnetic storm, the auroral zone will expand to lower latitudes.
During a geomagnetic storm, the auroral zone expands to lower latitudes.
The auroral zone is typically 10° to 20° from the magnetic poles.
A geomagnetic storm expands the auroral zone to lower latitudes.
During a geomagnetic storm, the auroral zone expanded to lower latitudes.
The zone for 'Aurora' creation is 10 to 20 degrees from magnetic poles.
During a geomagnetic storm, the visible auroral zone expands into lower latitudes.
During a geomagnetic storm, the auroral zone will expand to lower latitudes.
Although, during a geomagnetic storm, the auroral zone expands to lower latitudes.
The highest geomagnetic activity and greatest disturbances are observed in the auroral zone.
The greatest geomagnetic disturbances are observed in the auroral zone.
When a bright aurora is seen in the auroral zone, a strong magnetic disturbance is usually also observed there.
The auroras occur mainly in the regions near the poles in an area aptly named as”auroral zone” (between 65 and 75 ° latitude).
