“Just in case you did not know... Just for the sake of record keeping, the highest daily solar flux value during the entire previous Cycle 24 was 237 on January 7, 2014.”

@N4JAW do you have any suggestions on a concise primer to space weather? I under what the different metrics are measuring, but I don't know how to extend that to predicting how it will effect radio propagation.

@nn3x @N4JAW I had a similar question. I found this on the web and it was pretty informative. From the 2005 FDIM Symposium, a paper on Solar Activity & HF Propagation. TL:DR read the last page 😃https://www.qrparci.org/resource/FDIM81.pdf

@CavedaleRhones @nn3x That paper is what got me interested in Space Weather years ago.

@N4JAW I've been on 10M before lunchtime on FT8, tons of signals from across the pond. 2W got me a contact from Detroit to France
