Thanks for the info. I saw two bright ones last night in a few minutes without even trying about 10pm. Long and slow without much trail. Yellowish. Tonight should be better as they ramp up to the peak on 13/14. S&T article Dec 2006 p72 with a nice plot but don't understand about 'braving the cold' and 'freezing in the dark' they mention. Brian?
