(meteorobs) Quadrantids 2005 Jan. 3 from Oregon

[Wesley Stone]

Skies cleared off before midnight for me.  I was afraid of fog, but a brisk wind kept it at bay and hustled the scattered clouds away.  It was actually fairly comfortable, as the temperature didn't drop below 20F.  The Moon and snow cover meant skies weren't the best, and the orientation of the trees in my yard forced me to choose a slightly obstructed field of view to keep the Moon out of my eyes.  Quadrantid rates were a bit lower than I expected; most of the Quadrantids were faint and short and near the radiant.  There was one nice -3 yellow Quad with a short train.  I saw 78 total meteors in three hours.
