U. Munari and A. Siviero. Istituto Nazionale di Astrofisica, Padova Astronomical Observatory; S. Moretti, M. Graziani, and S. Tomaselli, Associazione Ravennate Astrofili Rheyta; and L. Baldinelli and A. Maitan, Osservatorio Paolo Pizzinato, Bologna, write that the symbiotic nova BF Cyg is on a rapid rise to a large-amplitude outburst. It took a whole century for BF Cyg to return toward quiescence following the outburst that peaked at B = 9.7 in 1894 (Leibowitz and Formiggini 2006, MNRAS 366, 675). The authors have tightly monitored the object as part of the ANS Collaboration and have found the brightness of BF Cyg to be stable during 2006 around the mean values U = 11.64, B = 12.50, V = 11.84, R_c = 10.45, I_c = 9.37. However, on July 31 the star started brightening, slowly at first and now much faster. The last measured values are U = 9.69, B = 10.34, V = 9.89, R_c = 9.31, I_c = 8.63 on Aug. 14.94 UT, and V = 9.75, R_c = 9.27, I_c = 8.59 on Aug. 15.86. The last time that BF Cyg was seen this bright in the blue was around 1925, during its decline from the 1898 eruption.
