Solar Flux
Overall Solar Activity on 10.7cm. From 62.5 to 300, higher better
150
Sunspot Number
Derived from num of sunspots + groups. From 0 to 250, higher better
88
A-Index
Average Geomagnetic Activity
12
K-Index
Geomagnetic Field Disturbance. From 0 to 10, lower better
5
Aurora Latitude
Estimated equatorward auroral oval latitude (both hemispheres)
62.5 °
X-Ray
Intensity of X-Rays in Ionosphere. A, B, C, M, X Indicates Magnitude
C1.0
Geomagnetic Field
Overall activity of Earth's magnetic field. Based on K-Index
MIN STRM
Signal Noise
Noise Contributed by Solar Activity
S4-S6
MUF
Maximum Usable Frequency for your QTH & current sun angle. Uses foF2 if reported, otherwise estimated from SFI.
N/A
Solar Wind
Speed of Solar Wind in KM/s. Typically 0-1000, lower better
597.9
Proton Flux
GOES satellite >10 MeV proton flux (pfu). ≥10 pfu triggers NOAA S1 radiation storm alert. Can cause polar cap absorption (HF blackout).
9
Electron Flux
GOES satellite >2 MeV electron flux (particles/cm²/sec/sr). High values indicate solar storm activity affecting satellites and correlating with HF disruption.
1370
F2 Critical Frequency
Highest Frequency that reflects back from F2 Layer (foF2)
