We, as yet, know very little about these three, supposedly unrelated, comets that rounded the Sun fairly close together.
Given their proximity one would normally think that they were 3 fragments from the same parent comet. Current consensus, though only based on minimal study, is that they are NOT fragments. Basically unrelated. Strange, but can happen.
Very small. Went undetected until spotted, after the fact, on SOHO images.
Have NOT been given MPC designations as yet because we don’t have enough observational data.
The first set of imaging is by veteran comet hunter Terry Lovejoy — who has discovered 6 comets. He knows his stuff & his forte is astrophotography. His pictures show that one fragment has brightened noticeably. This could be because it is getting ever closer to the Sun and as such continuing to become more ‘active’ — i.e., ‘evaporate’ giving out gases.
The comet has definitely fragmented. Of that there is no doubt or debate. The ‘orange’ Hubble picture shows 4-fragments and JPL (2nd image) already lists 5.
As the orbital diagram shows the ‘comet’ — or to be more precise — the fragments are still a longways out and we are moving away.
The fragments may be bright, but they are SMALL. So naked-eye visibility is questionable.
