Magnetic Indices

The k-indices are computed for three Canadian observatories, Ottawa, Meanook, and Victoria. These indices are also used in the production of the kp index or other planetary indices. For details on the production of Canadian k-indices and derivatives, please refer to the K indices information page.

Provisional hourly ranges, hourly means, and maximum rate-of-change values are produced for all Canadian CANMOS observatories. They are available 15 minutes after the data hour. For details on the production of these local indices, please refer to the Hourly range information page.


Canadian K indices and hourly ranges are products created by this organization and are offered in an accessible HTML alternative by selecting the HTML link in the list below. Kp indices and other planetary indices are produced by other institutes and therefore we can not offer a text friendly alternative.
