HF Propagation 高频传播  http://www.hamqsl.com/solar3.html#hfprop
Oct 7 2020 - HAMQSL Updates and Upgrades in Progress
Items completed:
  • Special thanks to Andrew KC2G and Alan N5PA for identifying a reliable source for MUF for Athens,GR; Hermanus,ZA; Sondrestrom,GL; Alaska,US; Niue IS; Darwin,AU; Tromso,NO; Mawson,AQ; Jicamarca,PE; Port Stanley,FK; Ascencion IS; Jeju IS; and Millstone Hill. This has been fixed on all selectable MUF banners, and specifically the marston.php and solarmuf.php banners. Data updated every 10 minutes and validated to be less than 1 day old (otherwise displays No Report)
  • Site is secure SSL from Clouldflare. Just substitute https:// vs http:// in the banner links
  • Separate CRON job for Boulder MUF updated every 10 minutes and validated to be less than 1 hour old (otherwise displays No Report)
  • CRON jobs fixed so data and images are once again updated every 30 minutes
  • Background X-Ray and Flare strength (both used in predicted forecast for all bands) fixed (new reliable source)
  • Proton & Electron Flux fixed (new reliable source)
  • Boulder MUF, fof2, and MUF factor fixed (new reliable source thanks to Alan N5PA)
  • xml and rss outputs updated (with new sources)
  • Updated NOAA SWPC WSA-Enlil Coronal Mass Ejection (CME) Solar Wind Prediction pages
Items in progress:
  • 6m North America propagation
  • If you have a source please let me know. Understand I will need their permission, and so far at least one reliable source has refused.
Broken links and outdated information as well as new data as it becomes availablePlease let me know if I break/or you see anything while fixing these issues. Lets hope the lousy Solar Cycle 25 forecast is totaly wrong (as have been in the past).

  • Select desired item from box. Page refresh updates all images at once.
  • On the dial background color schemes, green indicates that values in this range are unlikely to disturb the near-Earth space environment. Yellow indicates that values in this range may contribute to disturbances, and Red indicates that values in this range are likely to drive disturbances. This scheme is valid for all dials except the "Log[Beta]" dial
