We present results of applying feature tracking to a sequence of Hinode magnetograms. The single line wing Na
D 5896 magnetograms have a high signal-to-noise ratio, allowing the detection of flux approximately 30 times
weaker than in MDI magnetograms. We find evidence that, even with Hinode's improved resolution and sensitivity,
we do not always detect the bipolar emergence of new magnetic flux. This suggests that we have not reached the
ultimate resolution to observe the fundamental flux generation processes in the photosphere.
