The light curve of the flaring blazar CGRaBS J0211+1051 (ATel #3120, #3127, #3129, #3131) spanning 7 years (Jan. 2004 - Jan. 2011) obtained by CRTS shows a steady rise over the past ~3 years from ~15.6 mag in 2008, to ~13.5 mag on 24 Jan 2011, with superposed rapid variations on a ~ month time scale with amplitudes ~ 0.5 - 1 mag. There were also two sharp flares, in mid-Nov. 2006 (peak magnitude ~ 14.2) and in early Sept.2007 (peak magnitude ~ 14.4).
