hamateur 1953 Posted March 2 Share Posted March 2 https://www.spaceweather.gc.ca/forecast-prevision/solar-solaire/solarflux/sx-5-flux-en.php For radio amateurs ( Hams) that like to watch the flux on a daily basis the above link provides it three times daily 17:00 20:00 23:00 UTC from March until November and 18:00 20:00 22:00 UTC from November until March. There are archived measurements going back a few years if you are interested in these figures as well. OBS or observed flux is typically used as the reported value for the day at local noon or 20:00 UTC. This is the first column you encounter when scrolling down the screen. More flux the better!! 73 Mike N7ORL 1 1 Link to comment Share on other sites More sharing options...

Your clear explanation of the observed flux at specific times and the indication that higher values are beneficial for communication is appreciated. Wishing you excellent conditions and successful radio activities! -. 2 Link to comment Share on other sites More sharing options...

Thanks! @Newbie Although other hams may not follow it as closely as I do, it is interesting to correlate observed flux with actual operating conditions. I wish it was linear but you can’t have everything! Mike. 1 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted March 16 Author Share Posted March 16 Well heck. Too much time had elapsed for me to successfully edit the introductory topic, but because of my recent observations of hard X rays having apparently a direct effect on our E layer that Hams use for communicating, I began to wonder about the actual chunk of bandwidth of radio frequencies that NRC monitors and publishes daily. It is a pretty good chunk at 100 mhz! The center of which is actually listed as F 10.7 and radio astronomy no doubt knew this, but I never thought to check bandwidth until rereading a comment by @Philalethes in an earlier post.

hamateur 1953 Posted March 24 Author Share Posted March 24 Interesting 20:00 SFI was reported as 209 when observed SFI was actually 211 although adjusted flux was 209. Either an error or perhaps a judgement call by NRC or ? A 380 was reported and corrected once as I recall during an x event. Mike Link to comment Share on other sites More sharing options...
KW2P Posted March 24 Share Posted March 24 Yeah, 209, my, my, my. And I ought to be able to get on the air tomorrow. Whoo hoo. Work is done. No thunderstorms ahead. After a good night's sleep and some coffee it's Morse Code time. 1 Link to comment Share on other sites More sharing options...

KW2P Posted March 24 Share Posted March 24 Well, day off today and I was all ready to get on the radio but wasn't expecting a storm quite this strong. Instead I'm watching this G3 (so far) storm, wishing I was in Northern Siberia for a few minutes to see the show. We have a radio blackout in the Western Hemisphere, too. High X-ray flux. Might be a good time to cook some food instead. 1 Link to comment Share on other sites More sharing options...

( 50 mhz) like I have never seen before. It appears that @tniickck was correct after all. This event is probably a combination of coincidental events as a guess. Unfortunately my grid square in CN 87 is void of activity 🤣🤣. Wow. What an event. It wiped out all of the lower frequencies we typically use and ionized the heck out of our E Layer it would appear. 1 Link to comment Share on other sites More sharing options...

And after solving my lack of 80 and 30m antennas, need to do something about six meters. 1 Link to comment Share on other sites More sharing options...
