We continue the photometric monitoring of the FUor star HBC 722 (see also ATel #2801, #2808, #2819, #2854, #3040, #3165) in the field of NGC 7000/IC 5070. The recent BVRI photometric data were obtained with the telescopes of the National Astronomical Observatory Rozhen (Bulgaria). The outburst of HBC 722 was detected during the summer of 2010 (Semkov et al., 2010, A&A, 523, L3; Miller et al. 2011, ApJ, 730, 80) and up to September 2010 the star brightness increased by 4.7 mag (V).
