We call your attention on our recent observations of the the QSO CGRaBS J1824+5651 (z=0.664), cross identified with the Gamma Ray source 2FGLJ1824.0+5650. On May 28th,2014 (JD2456805.9719), we found this blazar to be in an outburst. On this date, the source was found to have a flux corresponding to H = 13.491 +/- 0.04. It is a flux about 2 times larger than our previous NIR photometry H = 14.159 +/- 0.03 on JD 245661161. It is brightest since we started monitoring this source on JD2455331. We encourage further multiwavelength observations.
