We have observed a recent NIR flare of the intermediate redshift Narrow Line Seyfert galaxy PMN0948+0022, z=0.5846. This source is cross identified with the gamma ray source 1FGLJ0948=0022 and the optical source BZQJ0949+0022. From observations carried out on December 18th, 2012 (JD 2456279.99788), we determined the following photometric values H = 13.241 +/- 0.08, J = 14.352 +/- 0.11 and Ks = 12.683 +/- 0.07. These values correspond to the brightest state of this source since JD2454924.681163, when we started monitoring this source at NIR wavelengths. The source is now brighter that it was on June 2011 when it showed an X-ray and gamma ray flare activity, reported in Atel #3448 Atel #3429. It has been reported to shown flaring in gamma ray emission (Atel #2733). Observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory operated by the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We strongly encourage further multi wavelength coverage.
