The formula to calculate the Apparent Magnitude (M) is:
\[ M = -5 \cdot \log_{10} \left( \frac{Fx}{Fx0} \right) \]
Where:
Apparent magnitude is a measure of the brightness of a celestial object as seen from Earth. It is calculated by comparing the observed irradiance of the object to a reference flux. The lower the apparent magnitude, the brighter the object appears.
Consider an example where:
Using the formula to calculate the Apparent Magnitude:
\[ M = -5 \cdot \log_{10} \left( \frac{1.5}{1.0} \right) \approx -5 \cdot 0.1761 = -0.88 \]
This means that the apparent magnitude for this example is approximately -0.88.
