We call attention on our recent observations of PKS J0808-0751 with the Cananea NIR camera (CANICA) on the 2.1m telescope at the Observatorio AstrofÃsico Guillermo Haro. We found that this quasar
shows a flux increase of 3.5 magnitudes in the Ks bandpass during the past year.
Below, we list our photometric results for this period.

PKS J0808-0751 is a quasar positionally coincident with the bright mm source
WMAP J0808-0750, listed before as source 133 (Bennett et al. 2003, Wright et al 2009).
This source has been tentatively associates with 3EG J0812-0646. At this point, We consider this object a high priority target for space borne gamma-ray observatories in order to confirm
this association, as the object should show a significant flux increase at all wavelenghts.Hencefore, we encourage multi-wavelength monitoring of this object.
