"O cometa Kohler foi o mais brilhante do ano de 1977, sendo caracterizado por seu período extremamente longo e pela presença de uma coma difusa com condensação central, representando o núcleo. Neste trabalho, foram deduzidas, semi-empiricamente, as taxas de produção de água (H2O) e hidroxila (OH) desse cometa. Assim, foram estimados seu raio nuclear mínimo, de cerca de 0.9 ± 0.45 km, e seu raio efetivo, de 3, 0 ± 1, 5 km. Os resultados foram comparados com aqueles obtidos em observações de rádio a λ = 18cm, em fotometria de banda estreita, e com cometas jovens de longo período (YL) recentes, cujas taxas de produção de água foramanalisadas por [1]."

"The Kohler comet was the brightest of the year 1977, being characterized by its extremely long period and the presence of a diffuse coma with central condensation, representing the nucleus. In this work, the rates of production of water (H2O) and hydroxyl (OH) of this comet were deduced, semi-empirically. Thus, its minimum nuclear radius of about 0.9 ± 0.45 km and its effective radius of 3.0 ± 1.5 km were estimated. The results were compared with those obtained in radio observations at λ = 18cm, in narrowband photometry, and with recent young long-period (YL) comets, whose water production rates wereanalyzed by [1]."
