SUMMARY

The discussion clarifies the distinctions between Solar Radio and Radio Flux 10.7 cm, confirming that they are related but not identical measurements. Radio Flux 10.7 cm specifically refers to the daily observed flux at 2800 MHz (10.7 cm) in solar flux units (10-22 W m-2 Hz-1), while Solar Radio encompasses multiple frequencies and is measured in the same units. The F10.7 index serves as a critical indicator of solar activity, reflecting the heating of coronal plasma in active regions. The discussion also raises questions about the measurement periods and missing data in Solar Radio Flux records.

PREREQUISITES
  • Understanding of solar radio emissions and their significance
  • Familiarity with the concept of solar flux units (SFU)
  • Knowledge of radio frequency measurements, specifically at 2800 MHz
  • Basic comprehension of solar activity indicators, such as the F10.7 index
NEXT STEPS
  • Research the implications of Solar Radio Flux on space weather forecasting
  • Explore the relationship between solar activity and radio emissions at various frequencies
  • Investigate the historical data trends of the F10.7 index since 1947
  • Learn about the equipment used for measuring solar radio emissions and their operational periods
USEFUL FOR

Astronomers, astrophysicists, and researchers in solar physics will benefit from this discussion, particularly those focusing on solar activity and its effects on space weather.

Referring to following links, I would like to know whether Solar Radio is equal to Radio Flux or not, it seems that it describes Solar Radio in different format.

Are they monitoring the same objects?
Does anyone have any suggestions on what the different is between them?

Thanks in advance for any suggestions

The site says the following:
Forecasts of 10.7 cm solar radio flux are integer forecasts of the daily observed flux at 2800 Mhz (10.7 cm) in solar flux units (10-22W m-2 Hz-1)

Your second link has multiple frequencies listed, not just the 10.7 cm wavelength, but they are measured in the same units.

Thanks you very much for suggestions

I get some questions not understand well about Solar Radio Flux.

Questions about Solar Radio Flux

Referring to following image, I would like to know how to define the measured units for Solar Radio Flux.

http://www.swpc.noaa.gov/ftpmenu/lists/radio.html

For example,

Under column for 0500 UTC, will it refer to period starting from 0500 UTC to 1200 UTC?
Under column for 0500 UTC, will it refer to period starting from 2300 UTC to 0500 UTC?


Under the row for 410 Freq MHZ, wiill it referring to range starting from 245 to 410 Freq MHZ?
Under the row for 410 Freq MHZ, wiill it referring to range starting from 410 to 610 Freq MHZ?


Referring to following linked image, the data for solar radio flux are always missing for periods 500 UTC and 1200 UTC.
Do you have any suggestion? Will equipment be turned off during this period?

Thanks you very much for any suggestions

Referring to following link, F10.7 represents a measure of diffuse, nonradiative heating of the coronal plasma trapped by magnetic fields over active regions. Does it represent a measure of amount of charges particles within plasma as well? which is Electric Flux Density.

I am so confused, does anyone have any suggestions?
Thanks everyone very much for any suggestions

Solar radio flux
Emission from the Sun at centimetric (radio) wavelength is due primarily to coronal plasma trapped in the magnetic fields overlying active regions.[17] The F10.7 index is a measure of the solar radio flux per unit frequency at a wavelength of 10.7 cm, near the peak of the observed solar radio emission. F10.7 is often expressed in SFU or solar flux units. It represents a measure of diffuse, nonradiative heating of the coronal plasma trapped by magnetic fields over active regions, and is an excellent indicator of overall solar activity levels. The solar F10.7 cm record extends back to 1947, and is the longest direct record of solar activity available, other than sunspot-related quantities.
