Re: [IRCA] propagation article



This is one of these "I don't know why I bother bookmarking anything" moments. It's the Canadian government, so the websites will be shuffled around on a weekly basis. I should just create a bookmarks list that links to "404"

OK, rant over.  Some searching gave me these soon to be out of date links:

http://geomag.nrcan.gc.ca/plot-tracee/ssp-1-en.php gives you the last 24 hours of magnetic observatory plots, but it's raw, no K-indices which are only calculated for three southerly observatories http://geomag.nrcan.gc.ca/data-donnee/indices/si-en.php will get you historical K-indices for those observatories, but it's months out of date

Otherwise http://geomag.nrcan.gc.ca/data-donnee/indices/si-vi-en.php?type=hourly_ranges will get of raw geomagnetism at all the observatories until quite recently.

They have a plotting service, which which also shows you a map of the magnetic observatory locations:

http://geomag.nrcan.gc.ca/plot-tracee/mp-en.php?format=html

but again, raw geomagnetism.   Anyone know how to calculate K indices?

I have heard that "IT technicalities are preventing us from automatically providing up to date k indices on the web site.", so possibly some day they may return?

They used to have a mailing list to which you could subscribe, but that has also been shot down by
"IT technicalities ".

There still is a service to which you could subscribe, which predicts daily geomagnetic conditions in the sub-auroral, auroral and polar cap regions, but darned if I can find out how to become a new subscriber. I may be able to find out if anyone is interested, but I'd hate to shoot down a skunk works operation, hi.

best wishes,

Nick
