Location of the comet without any problem due to its size and luminosity. Estimation with the star Phi BOO 5.26 with the naked eye since Chambéry is in light restriction the stars are coming back.

The comet located west of the star HD 140831 (m 8.56) develops a round hair with the eccentric core on the west side and a very thin tail oriented north over a distance of about 25', close to the moon diameter. Comet not visible to the naked eye.

A nice sighting.
