DAILY ESTIMATED SUNSPOT NUMBER
- red dots, "SC": prediction method based on an interpolation of Waldmeire's standard curves; it is only based on the sunspot number series
- red dashes, "CM": method combining a regression technique applied to the sunspot number series with the a geomagnetic index used a precursor (improved predictions during the minimum phase between solar cycles).
"The Weak Signal Propagation Reporter Network is a group of amateur radio using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power ( QRP/QRP/p ) transmissions. The software is open source, an the data collected are available to the public through the site http://wsprnet.org."
