  The Telescope Array Collaboration has observed an excess of events with $E
\ge 10^{19.4} ~{\rm eV}$ in the data which is centered at (RA, dec) =
($19^\circ$, $35^\circ$). This is near the center of the Perseus-Pisces
supercluster (PPSC). The PPSC is about $70 ~{\rm Mpc}$ distant and is the
closest supercluster in the Northern Hemisphere (other than the Virgo
supercluster of which we are a part). A Li-Ma oversampling analysis with
$20^\circ$-radius circles indicates an excess in the arrival direction of
events with a local significance of about 4 standard deviations. The
probability of having such excess close to the PPSC by chance is estimated to
be 3.5 standard deviations. This result indicates that a cosmic ray source
likely exists in that supercluster.
