We performed photometric and polarimetric observations of a sample of gamma-ray blazars at the Perkins telescope (Flagstaff,AZ) operated by Boston University using the PRISM camera in R band
from 24 September to 28 September 2022. During these 5 nights the quasar 3C454.3 shows a steady increase of the flux density and fractional polarization. The brightness increased
from R=15.348+-0.005 on September 24 to R=14.643+-0.004 on September 28, while the degree of polarization increased from P=2.35+-0.24% to P=12.36+-0.32%.
Multi-wavelength observations are encouraged.
