Hi Andrew,

Once e is established to be below 1.0 don't they relabel C/ as P/ ?

Not certain as to when they re-designate Andrew but with the orbital elements jumping around quite a bit until a longer track is observed it's
probably too early to say with great certainty.
True, e=1.0 at the moment (so the orbit appears parabolic implying a once-only pass) but figures might change so we'll know more certainly whether it is a first-timer or not in a few weeks I guess.
Best,
