The quasar 3C 279 shows a significant increase of optical activity during the last 10 days. According to monitoring at the Perkins telescope, (Flagstaff, AZ), AZT-8 (Crimean Astrophysical Obs.), and LX-200 (St.Petersburg Univ., Russia) telescopes the magnitude in R band has changed from ~15 to ~13.8 and the degree of polarization (P) has risen from 3% to 30%, while the position angle of polarization (EVPA) rotates: observations on March 11 at the AZT-8 telescope are (R=14.936+- 0.002 P= 6.66+-0.23% EVPA= 99.7+- 1.0deg), on March 17 at the LX telescope are (R=15.117+- 0.011 P= 3.2+-0.72% EVPA= 150.8+- 6.2deg), and at the Perkins telescope on March 21 and 22 - (R=14.413+- 0.008 P= 19.4+-0.23% EVPA= 28.7+- 0.3deg) and (R=13.845+- 0.013 P= 30.2+-0.35% EVPA= 31.4+- 0.3deg), respectively. Multi-wavelength observations are encouraged.
