The Extreme Optical Variability of J0948+0022
  We report on observations of the optical variability of the radio-loud,
narrow-line Seyfert 1 galaxy J0948+0022 on time scales ranging from minutes to
years. Implications regarding recent suggestions that the object may constitute
a prototype for an emerging class of blazar-like objects similar to FSRQs are
discussed. The optical microvariability observed for J0948+0022 is found to be
similar to that found for a typical LBL blazar. Based on observations of
J0948+0022 in a flaring state and a significantly lower state, one can
demonstrate that these rapid variations are most likely originating in the
relativistic jet and not in the accretion disk
