   Unlikely.  Maciej Reszelski reported gamma CMi separatedly.

   The conclusion in this case would be that accuracy of PIXY measurements
is too poor, possibly worse than visual observations.  Yoshida-san might
need to flag the observations that "these measurements are so unreliable
that anyone should not use them for scientific purpose" X-)
