We call attention on our recent observations of QSO B0133+47 with
the Cananea NIR camera (CANICA) on the 2.1m telescope at the
Observatorio Astrofísico Guillermo Haro. We found this quasar
to show fluxes 2.5 magnitudes brighter than 2MASS values, of epoch 1999,
but undergoing a rapid decline:

H = 12.356 ± 0.01 at JD 2454788.761732
H = 12.440 ± 0.03 at JD 2454790.816569
H = 12.769 ± 0.02 at JD 2454794.642166

QSO B0133+47 is positionally coincident with the bright mm source
WMAP 80 (Bennett et al. 2003) and the VHE photon 1379 (Thompson,
Bertsch, O'Neal Jr. 2005) and we consider it of high interest for
space borne gamma-ray observatories. We encourage multiwavelength
monitoring of this object.
