By July it was apparent that it was fully CO depleted. Some had postulated that this comet was about 2km in size and that it was just not producing much in terms of output and was fairly dim for its placement near us. But it became increasingly obvious that the non-gravitational forces were moving this object out of the predicted orbit much too easily. To many this break up validates the theory that comets are just a loose aggregate of various ices and some other solids. However, this may be a very broad pen in which to paint all comets.
Some comets seem to act differently in nearly the same conditions.
It may very well be that most are similar to this description but not all. More needs to be researched. The premiere comet website Comet Linear.
