Whereabouts of McNaught striations

After two unbroken weeks of overcast (last caught the comet in evening
twilight a few days before perihelion), there is some chance of clearing
at least by tomorrow night. I'm wondering whether there is a point
(especially with the Moon waxing) to heading out and trying to image
the northern striations from the comet tail. Can someone give me
the latest on where they can now be traced to in the sky? (I'm
at about latitude +33, and in envy of the folks who've been seeing
them so far).

Thanks,

Bill Keel
