The graph is the DAILY sunspot count, not monthly. Sorry(tm). Picture from 7-18, http://www.latimes.com/science/scien...718-story.html Well, we have the Maunder Minimum which lasted about 70 years, the Dalton Minimum which lasted 40 years, and a few others that lasted maybe 5 years. All corresponded to global cooling and miniature ice ages. That begs the question whether a one day drop in the sunspot count is worthy of a unique name. Certainly some governing body could award the naming of a sunspot minimum to the first observer who notices the lack of sunspots. I would volunteer to be the first to have a one day sunspot minimum named after me, but since I wasn't the first to notice, the prize should go to someone else. More to the point of this group, the 2.8GHz (10.7cm) solar flux follows the sunspot cycle. For propagation, I guess that's more interesting than counting suspots. http://www.spaceweather.gc.ca/solarflux/sx-eng.php Last 7 days data: http://www.swpc.noaa.gov/ftpdir/lists/radio/7day_rad.txt Looks like 2.8GHz radio flux dropped as fast as the sunspot count. http://www.swpc.noaa.gov/ftpdir/indices/quar_DSD.txt Solar update from the ARRL. http://www.arrl.org/news/the-k7ra-solar-update-331 Lot of good links and reading included. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
