Its orbit is hyperbolic, so it is not a closed one. If further observations confirm the unusual nature of this orbit, this object may be the first clear case of an interstellar comet”. Williams (from 34 observations spanning 2018 Aug. 13, when the magnitude was given as 21.2-21.4, 23.5, and 22.7-23.5, respectively), the following elliptical orbital elements by G. 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. The available astrometry (including additional pre-discovery Pan-STARRS2 observations from 2018 Oct. The Salted Peanuts Effect: Developed interest in scanning technology. As it turned out, GSC did not involve Dave. 1 year design 1 year build 1 year execute. Unless there are serious problems with much of the astrometry listed below, strongly hyperbolic orbits are the only viable solutions. The Guide Star Problem: 4 coverage 1 color astrometry+photometry. Williams, Associate Director of the Minor Planet center, wrote: “Further observations of this object are very much desired. Images were obtained and measured by Michael Schwartz and Paulo Holvorcem and astyrometry was published on the discovery circular by the Minor Planet Center. The comet C/2017 U1 is the dot of light in the center of the frame. The images above were captured with the 32″, “Big Blue” robotic reflector available at Tenagra Observatories, as part of its work covered by the NASA grant #NNX15AE89G. News: see our new image of A/2017 U1 here. Updates: The Minor Planet Center issued a new Circular where the object has been renamed A/2017 U1: no cometary activity was detected in deep imaging.
