Results of the IMO Video Meteor Network - January 2010

The weather across the IMO Video Network was poor in 2010 January. Still, 25 observers operated 39 cameras on all nights. More than 6000 meteors were recorded in more than 1500 hours of observations. The descending activity branch of the Quadrantids was well covered on 2010 January 3/4. High-resolution analysis of the video data covering years from 1993 to 2010 is presented. An asymmetric activity profile is discovered, with a steeper ascending branch and a gradual descending branch. The FWHM of the Quadrantids from the long-term video data is about 0.7 deg.
