The quasar 3C454.3 shows an increase of the optical activity during the last three nights. According to our observations at the Perkins telescope of the Lowell Observatory (Flagstaff, AZ) the brightness of the source on June 10 (JD 2457549.8770) in R band was 15.817+-0.018 with a of polarization of 2.27+-0.39%. On June 12 the brightness and degree of polarization increased significantly
(R= 15.262+-0.018 and P=13.00+-0.25%) and the last night a new increase of the brightness is observed (R=14.958+-0.020).
We encourage multi-wavelength observations of the quasar, well known for its dramatic variability and a good correlation
between variations at different wavelengths from gamma-ray to mm-waves.
