We report on the new NIR flare of the high redshift QSO PMNJ2301-0157 (z=0.778), cross identified with the source BZQJ 2301-1058. On November 4th,2020 (JD 2459157.8084), we found the source with the following fluxes in the NIR: J = 13.812 +/- 0.04, H = 13.073 +/- 0.04 and Ks = 12.156 +/- 0.05. This is to be compared with our previous observations on JD 2458027, when the source flux corresponded to H = 15.949 +/- 0.04. Hence, the source has had a flux increment of a factor of 14 in this lapse. This object has presented flaring activity in the past (ATEL#8208,ATEL#9817). Our observations are 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 multiwavelength coverage. Related
