I've seen OAO-3 (Copernicus) flare quite frequently on passes, sometimes
to  -3 or so.  Usually only a single flare is possible on a given pass
from what I've observed, and I've probably seen 100.  This satellite,
before Iridium constellation, was high on my list for potential and
spectacular flares.  Enjoy!

Its older companion OAO-2 ( 68-110A), was observed flaring to mag -4
20 November 1997 by Rob Mcnaught at Bugalbie.
