The present investigation is concerned with the question whether comets are getting fainter, taking into account Halley's comet (1910II) which has been well observed for nearly two millenia. The values for the absolute magnitude of the comet provided by three different equations for the 1910 apparition are 5.88, 5.91, and 6.01, respectively. The values are all slightly higher than the 5.49 and 5.44 values obtained by Morris and Green (1982). Comets decay, and each time they pass the sun considerable amounts of gas and dust are emitted by the nucleus. A relative mass loss per perihelion passage of (2.3 + or - 2.3) percent is calculated. It is concluded that two thousand years ago the comet was about (0.5 + or - 0.5) magnitudes brighter.
