This page provides observation hints for currently observable comets. That includes orbital elements, ephemerides, visibility diagrams, comparison star maps, brightness parameters etc.
Important note! The magnitudes listed in the ephemerides can deviate more or less from the observed ones. Up-to-date magnitudes are available under News or under Photometry/Observation Results.
Elements & Ephemerides (ICQ)
The brightness parameters are also available as a text file.
A detailed explanation of the columns is given at the end of the table.

In some cases the comet's brightness evolves in a time-dependent manner (indicated in the table above by values n < 0.5), which can be described by the formula: m = M0 + 5×log (delta) + n×(t-T)
where:
delta = Distance Comet - Earth
r = Distance Comet - Sun
t = Date of observation
T = Date of Perihelion
In most cases the brightness evolution of a comet can be described by one set of brightness parameters for the whole apparition or by one set each for the pre- and post-perihelion period.
However, in some cases comets show a complex evolution. This is described in the appropriate analysis, but cannot be represented in this table. In these cases the table lists mean or representative values for the pre- and post-perihelion parameters, which may deviate significantly from the actually recorded brightness evolution. Therefore it is recommended to study the appropriate analysis beside this table.
The column VoP indicates the complexity of the brightness evolution of a comet, in the case I analysed it. The meaning of VoP is as follows:
| VoP | Description |
| S | The comet showed a uniform brightness evolution throughout the apparition which is well represented by the tabulated values |
| C | The comet showed a complex brightness evolution -> the actual evolution has to be extracted from the analysis |
| S S | The comet showed different but uniform brightness evolutions, pre- and post-perihelion, which are well represented by the tabulated values |
| C C | The comet showed different, complex brightness evolutions, pre- and post-perihelion -> the actual evolution has to be extracted from the analysis |
| S C | The comet showed different brightness evolutions, pre- and post-perihelion. Pre-perihelion the brightness evolution was uniform and is well represented by the tabulated values. Post-perihelion the brightness evolution was complex, therefore the actual evolution has to be extracted from the analysis |
| C S | The comet showed different brightness evolutions, pre- and post-perihelion. Pre-perihelion the brightness evolution was complex, therefore the actual evolution has to be extracted from the analysis. Post-perihelion the brightness evolution was uniform and is well represented by the tabulated values |
| - | the tabulated values have not been verified in any detailed manner by myself (simple deduction from the discovery brightness, brightness parameters taken from a former apparition, values taken from other comet-related sources etc.) |
I have analysed apparitions of brighter comets since 1973. However, only those analysis which I prepared since mid-1996 are online so far. I intend to make the pre-1996 analysis available online during the coming years.
