  Shot noise measurements provide information on particles' charge and their
correlations. We report on shot noise measurements in a ubiquitous quantum dot
under a quantized magnetic field. The measured noise at the peaks of a sequence
of conductance resonances was some nine times higher than expected; suggesting
bunching of electrons as they traverse through the dot. This enhancement might
be mediated by an additional weakly coupled level to the leads or an excited
state. Note that in the absence of magnetic filed no bunching had been
observed.
