The following table gives a summary of the comets brighter than 16 mag, which were observed by members of the German Comet Section.
The maximum brightness of comets brighter than 10.0 mag is given with an accuracy of 0.1 mag, that of fainter comets with an accuracy of 0.5 mag. The maximum coma diameter is given with an accuracy of 0.1' for comae less than 1', with an accuracy of 0.5' for comae between 1' and 5' and with an accuracy of 1' for larger comae.
