[IRCA] the average Ap index

[Nick Hall-Patch <nhp@xxxxxxxx>]

Interesting view of the continuing decline in the A-index:

Lowest it's been in a very long time, apparently, in spite of increasing
sunspots.   I saw one graph going back 165 years, but can't quickly find the source.

best wishes,

Nick
