C/2017 U1 (PANSTARRS) = P10Ee5V

Sam Deen

Dear all,

The candidate interstellar comet has been taken off the PCCP and is now C/2017 U1 (PANSTARRS)

The Discovery MPEC made an official comment on its notability:
     Further observations of this object are very much desired.  Unless there
are serious problems with much of the astrometry listed below, strongly
hyperbolic orbits are the only viable solutions.  Although it is probably
not too sensible to compute meaningful original and future barycentric orbits,
given the very short arc of observations, the orbit below has e ~ 1.2 for
both values.  If further observations confirm the unusual nature of this
orbit, this object may be the first clear case of an interstellar comet.
