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 Some searching gave me these soon to be out of date links: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historical K-indices for those observatories, but it's months out of date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

One thing we all agree on is the desire for very low geomagnetic activity
for TP/TA. I also think he's right that we should be looking at Canadian
Arctic K indexes. How do we find those? 73 KAZ
