Michael Mattiazzo
is predicting an "edge-on" view to the comet
at its best visibility.
This means the comet could become brighter than expected with a several degrees
long tail at the end of February. (Flyby of the Earth: Feb.24)
Ye Quanzhi performed
a particular anylysis of the last
Lulin
Observatory's image. He found at least 9 jets.
