Hey Chris,
I see quite a discrepancy between the Australian SWS real-time foF2 map:
http://www.sws.bom.gov.au/HF_Systems/6/5and the equivalent map on the HFU propagation page:
https://www.hfunderground.com/propagation/#ionosphereFor reinforcement, I got some contemporary data from North American ionosonde data and it much more closely aligns with the SWS than the HFU maps.
Since there is really only one source for real time ionosonde data, I am going to assume that map on the HFU page is
predicted by the software mentioned on the map and
not based upon real time measurements. Correct?
I realize that recent ionosonde data is featured here, later on the page:
https://www.hfunderground.com/propagation/#skipzonebut I would think that this could be made a bit more clear.
