It has already been more than two weeks since the discovery of the comet. A periodic circular has come out with improved orbital elements. The orbital variant with the close perihelion has been supported (perihelion date 4 September 2011), but so far the orbit looks parabolic. It is very probable that in time the eccentricity will become less than one and we will be able to calculate the orbital period of the comet around the Sun.
