Rob McNaught has found comet in the evening sky:

According to the Rob it may be quite a bit brighter than the above ephemeris predicts, although its likely to be a lot fainter than his bright one early this year.
Unfortunately, weather has prevented me from doing much comet searching myself lately otherwise I would have definitely had a chance at finding this one!
