Options for Historical Summary Plots
Three options for Data Source are available:
- preliminary - raw, unchecked data indicating the variation in the magnetic field. Available in near real-time.
- definitive - magnetic field data corrected for baseline variations. These data are not made available until some time after the event (typically a few months after the end of each year).
- best available - definitive data if available otherwise preliminary data. The type of data is labeled on the right side of the plot beside each of the stations.
Scale: (vertical)
- fixed scale is determined from the maximum positive and negative variations from the mean for all components for all stations.
- variable scale is determined from the positive and negative variations from the mean for all components for a station.
Plot style:
- solid displays the data using a solid line with gaps for missing data.
- dotted displays each data point as a dot.
Colour coding indicates the level of geomagnetic activity:
- Green indicates quiet conditions.
- Yellow, orange and red indicate increasing levels of activity.
More information about activity levels can be found at: http://www.spaceweather.gc.ca/sfst-eng.php.
