Sep 10 2020 - HAMQSL Updates and Upgrades in Progress
Items completed:
  • 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.
  • Reliable source for MUF from 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
    • If I cant find a reliable source for MUF from these regions I will be forced to discontinue the solarmuf banner and modifiy the others as required. If you have a source please let me know!
  • Broken links and outdated information as well as new data as it becomes available
Please 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).

Online Maximum & Lowest Observed Frequency (MOF & LOF) HF Propagation Prediction Tool

  • For 3,000 kilometer radio signal single hop paths (original tool Courtesy of K1TTT)
  • N0NBH Tool enhancements include a different global map, resolution & auto population of your location, and obtaining & auto population of current SFI, A-Index, and K-Index conditions
  • Just click "NOW" as all settings (including location) are auto-populated using the current NOAA solar data indices.
    • I resolve and populate your coordinates using your IP address. If not correct, just click your QTH location on map then click "NOW".
  • Select desired mode/map/overlays. Key shows bands.
  • Click "Next Hour" to advance one hour.
  • Enter desired future NOAA/SWPC predicted SFI, A-Index, K-Index, Month, Day, and UTC Time (current NOAA/SWPC 27-day Space Weather Outlook Table provided below), then click "Compute" for future predictions.
Java Update
Starting with Java 7 Update 51, java no longer supports running of unsigned java applets, and unfortunately it is cost prohibitive to add a digital signature to the MOFLOF tool. If you get an "Application Blocked by Security Settings" error loading the page, you can still use the online tool on your browser by changing the Java security settings in the Java Control Panel to medium (not recommended) or by adding http://www.hamqsl.com/ to the exceptions list and leaving the security level at "high"(recommended). Complete instructions are provided at this Java Settings page.

Online Solar Terrestrial Data Converters

Online Sunspot Number (SN)/Solar Flux Index (SFI) Converter

  • Converts SN to SFI, or SFI to SN. Useful for those programs that require one value, and you only have the other. Also fun to play around with!
  • Remember, you are using a measured or observed value to calculate the other using a recognized formula, so the result most likely will not match the other measured value. The solar panel only uses measured/observed values from NOAA.
SFI
(64-300)
SN
(0-250)

Online K-Index/K-Measurement Unit (nT)/Signal Noise Level/Geomagnetic Field Converter

  • Converts K-Index (from 0-9) to the K-Measurement Unit (in nanoTesla or nT) range, the expected HF signal noise level range in "S" units/dB, and the current Geomagnetic Field state
  • You can also enter a specific K-nT value (from 0-999), or specific signal noise level in "S"/dB (0-60), or Geomagnetic Field of Quiet, UNSET, Active, or Storm (any case) to get the other values/ranges.
  • Great for figuring out how noisy the bands are
K-Index
(0-9)
K-nT
(0-999)
Sig Noise
(0-60)
GeoMag Field
(Quiet|UNSET|
Active|Storm)

Online Aurora Activity/K-Index/Latitude Converter

  • Converts specific Aurora Activity (from 1-10++) to the calculated K-Index (from 0-9), and to the lowest Latitude (North or South Hemisphere) range in Ks that you can expect Auroral activity (either visual or radio frequency)
  • You can also enter a specific calculated K-Index (from 0-9), or specific latitude in "°"/Ks (40-90) to get the other values/ranges.
  • Great for figuring out when to get outside and look for the northern lights or work VHF Aurora at your location
Aurora
(0-10|
10+|10++)
K-Index
(0-9)
Latitude°
(40-90)

Online Solar Wind Converter

  • Converts specific Solar Wind Values to/from kilometers per second (kps) to/from kilometers per hour (kph) to/from miles per hour (mph). Data cannot be entered for time to earth in hours (display only).
  • Remember it rounds, so changes in mph may not impact kps.
  • Great for figuring out how long an event will take to get to earth at the current speed.
kps
(0-1000)
kph
(0-3,600,000)
mph
(0-2,236,936)
hours
to Earth
no entry
