What is different in Solar Radio vs Radio Flux 10.7 cm?

[junk0]

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.

Solar radio and radio flux 10.7 cm are two different measurements used to study the Sun. While they both involve radio waves, they are not equal to each other.

Radio flux 10.7 cm is a measurement of the radio emissions at a specific wavelength of 10.7 centimeters from the Sun. This measurement is often used as an indicator of solar activity and can be used to track changes in the Sun's overall magnetic field. It is typically measured by ground-based instruments and reported by organizations such as the National Oceanic and Atmospheric Administration (NOAA).

On the other hand, solar radio refers to the entire range of radio emissions from the Sun, not just those at a specific wavelength. These emissions can occur at different frequencies and can provide information about different phenomena happening on the Sun, such as solar flares or coronal mass ejections. Solar radio is typically measured by radio telescopes and reported in a different format than radio flux.

So while both measurements involve radio waves and are used to study the Sun, they are not equal to each other. They provide different types of information and are measured in different ways. It is important to note that they are not monitoring the same objects, but rather different aspects of the Sun's activity.

In summary, the main difference between solar radio and radio flux 10.7 cm is the type of information they provide and how they are measured. It is important to understand the distinction between the two in order to properly interpret and use the data they provide.
