About Noon 10.7cm Radio Flux
The 10.7 cm (2800 MHz) solar radio flux is a key indicator of solar activity. This measurement represents the solar radio emission at a wavelength of 10.7 centimeters (frequency of 2800 MHz) and is expressed in solar flux units (sfu).
Solar Cycle Correlation
The 10.7 cm radio flux (F10.7) closely follows the Sun's approximately 11-year solar cycle, making it an excellent indicator for tracking long-term solar activity trends.
Interpretation
- Below 100 sfu: Low solar activity
- 100-200 sfu: Moderate solar activity
- Above 200 sfu: High solar activity, potential for geomagnetic storms
Importance
The 10.7 cm radio flux is widely used in space weather applications, including:
- Predicting the intensity of the F-layer in the ionosphere
- Estimating the density of the thermosphere
- Assessing the likelihood of geomagnetic storms
- Monitoring solar activity cycles
