Summary of the brighter comets in 1987

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.

Explanation

discovered = Date of Discovery
T = Date of Perihelion
q [AU] = Perihelion Distance in AU
m_max = maximum brightness observed in the course of the year
Coma ['] = maximum coma diameter (in arcminutes) observed in the course of the year
FGK = Observation Method used by the members of the German Comet Section (V = visual observation, P = Photography, C = CCD / Digital Camera)
