Low excentricity comet C2008 T1 Boattini

On the night of October 1, a supicious object was posted on the NEO confirmation page. When I started imaging it, there were only few observations by the original discoverer (Andrea Boattini at Mt. Lemmon) and some other observatories. Local conditions were only marginally good (no Moon but mediocre seeing) and the body was crossing a star-populated field, so the only images I could take barely allowed to pinpoint is astrometric coordinates. The real cometary nature of this object was then confirmed by several other observers.
According to preliminary calculations by Brian G. Marsden, C2008 T1 is a very short-period comet that experienced a very close encounter with Jupiter in 2003.
