The only good match for the time, direction and location was Iridium 59.
However, Iridium 59 should not have been flaring up at this time (which
is the only reason it would get to magnitude +0).  If IR59 is experiencing
pointing problems, then it is possible that it could have briefly flared up
for you (which would explain why it appeared to fade to invisible soon
after you spotted it).
