From that article I make the peak about 6-10 am sunday our time.

It being overcast here at the mo, I think the point maybe moot.
If you are out, 1 am will be good from an angle point of view and no moon. Also (for UK) 7:06 pm the ISS is due over.

False-color image of a 2012 Orionid meteor, seen over Tullahoma, Tenn. (caption for the picture on the right sidebar)

I used to LIVE in Tullahoma, Tennessee, and I have family that lives there still.

I've my alarm set, and plans made. I'll also try to file a full report once it's over.
