Nota: [magnitud es una observación negativa de modo que el cometa se encuentra debajo de ese brillo con ese instrumento utilizado. >magnitud es usado cuando el cometa fue visto y el observador simplemente dice que era más débil que la magnitud dada.  magnitud: los dos puntos “:” indican quela magnitud no es muy exacta o hecha en pobres condiciones.  & Diámetros de coma y longitudes de cola aproximados.
