| magnitude |
One of the most important pieces of information gathered by amateur astronomers. This represents the estimated brightness of the comet when compared to stars around it. The term "m1" is used to represent the total or integrated brightness of the comet's coma, while "m2" represents the brightness of the nucleus. Observers estimate "m1" by usually memorizing the comet's appearance and then defocusing the surrounding stars to a size equivalent to the comet's coma diameter. ...

| magnitude |
The degree of brightness of a star or other object in the sky according to a scale on which the brightest star has a magnitude -1.4 and the faintest visible star has magnitude 6. Sometimes referred to as apparent magnitude. In this scale, each number is 2.5 times the brightness of the previous number. Thus a star with a magnitude of 1 is 100 times brighter than on with a visual magnitude of 6.
