Solar Conditions
|
Sunspots This value is calculated based on the number of sunspots and sunspot groups observed. This value ranges from 0 to 250, with higher numbers indicating better solar activity. |
122 |
|
Solar Flux This value measures overall solar activity at a wavelength of 10.7 cm. It ranges from 62.5 to 300, with higher values indicating better solar conditions. |
206 |
|
Geomagnetic Storms This value reflects the overall activity of Earth's magnetic field, based on the K-index. Higher values indicate more significant geomagnetic disturbances. |
UNSETTLD |
|
Solar Wind This value represents the speed of solar wind measured in km/s. It typically ranges from 0 to 1000, with lower speeds generally being better. Higher speeds can contribute to increased noise in radio signals. |
639.4 |
|
Signal Noise Level This value indicates the noise generated by solar activity, measured in S-units. It is calculated based on the interaction between solar wind and geomagnetic activity. Greater activity and disturbances in the solar wind lead to higher noise levels. |
