In photographic magnitudes this corresponds to roughly 9 mag ."
2.
Magnitudes obtained from this method are known as photographic magnitudes, and are now considered obsolete.
3.
The 1913 event was the brightest of the observed outbursts, reaching a photographic magnitude of 7.0.
4.
She initially analyzed 299 plates from 13 telescopes to construct her scale, which was accepted by the International Committee of Photographic Magnitudes in 1913.
5.
The photographic magnitude range was given as 7.7-8.8, but the variability was described as " somewhat doubtful ".
6.
The symbol for apparent photographic magnitude is " m pg " and the symbol for absolute photographic magnitude is " M pg ".
7.
The symbol for apparent photographic magnitude is " m pg " and the symbol for absolute photographic magnitude is " M pg ".
8.
The photographic magnitude range is given as 13.5-15.5, while a visual range is 10.60-11.74.
9.
A white supergiant of spectral type A2 / A3Iab, it is an Alpha Cygni variable that varies between apparent photographic magnitudes 6.57 and 6.62.
10.
Nowadays there is a mess of derived terms-" Absolute Visual Magnitude ", " Absolute photographic magnitude ", " Absolute bolometric magnitude "-and they're all different.
