C/2011 L6 Boattini
more info
Comet C/2011 L6 was discovered ny Andrea Boattini (Mt Lemmon) on 8 June 2011, that is about 4.5 months after perihelion passage. Soon, the comet was found on earlier images taken on 28 May 2011 with the Mount Lemmon Survey.
Comet had its closest approach to the Earth on 14 May 2011 (5.819 au), about three weeks before discovery.
C/2011 L6 was observed 0.91 yr in a range of heliocentric distances from 6.84 au to 7.42 au.
This comet suffers very small planetary perturbations during its passage through the planetary system that lead to a less tight future orbit with semimjor axis larger than 10000 au. (see future barycentric orbit).
