Seichi Yoshida cometa esto
"Now it is 8.5 mag (Jan. 6, Marco Goiato). In the Southern Hemisphere, it will be getting higher rapidly after this. However, the nucleus of the comet is not visible at all, fainter than 19 mag (Jan. 2, Robert McNaught). Probably the comet itself has already disappeared and only the remnant is visible. It will be fading rapidly after this. It is not observable in the Northern Hemisphere. "
Mas o menos quiere decir que el cometa, aunque tiene una magnitud Visual de 8'5, el núcleo tiene una magnitud superior a la 19, lo que querria indicar que es mas que probable que el núcleo se haya desintegrado, y lo que estamos observando son los remanentes del cometa.
