This diagram shows the data
for the last 24 hours from the Canadian CANMOS observatories. These data are received
by telemetry from each station and must be considered as
'raw' or preliminary.
For each station, the X (north), Y (east) and Z (vertical down)
components of the magnetic field are shown. Stations are displayed
starting with the most northerly at the top progressing down the
page in decreasing latitude.
Universal Time is used
, with the current time being at the right side of each plot frame.
All frames use the same scale (which automatically
adjusts to cover the largest variation), so that the relative strengths
of the field at different stations can be readily compared.
The background colour changes as the general level of activity varies:
- quiet - green
- moderately disturbed - yellow
- disturbed - red
