A recent Talkshop comment led me to look at a data directory where something tripped a thought
There is an earth affecting proton event dataset running from 1976, named SPE (Solar Proton Event). These are rare and erratic in time.
A very difficult maths problem is pulse density integration, one of the reasons why producing a statistical distribution shape is very hard where the data is sparse and spasmodic.
faked up innovated something visual, some kind of meaningful plot. Far from ideal so don’t be misled.
SSN is from SIDC
Taking the natural log of the energy value produces something sane looking, intuitively would be something like that. Added in some missing points for years with no events. Event data is provided to the second via NOAA.
This suggests solar frenetic activity does not follow SSN or radio noise as closely as usually assumed.
I see no reason why earth events are somehow a biased sample whereas trying to find all events without a platform is near impossible: we cannot see the “dark” side of the sun, even today with Stereo not well enough.
Also suggestve is a step up in activity during the 1980s.
The reader is left to ponder. Could upload a spreadsheet or CSV of the crude data decode I used. (good enough)
Ideas on how to do better are welcome. (integrative kernal functions are a bit above my pay scale… I pay to do this stuff, mad)
