ABSTRACT:Results are presented from high angular resolution (C-12)O line observations of the prominent small scale optical filament at the low-l, low-b boundary of the Draco nebula.A smooth CO distribution along the filament is observed with a steep intensity gradient at the tip of the filament.
The variations in CO intensity, the radial velocity, the line width, and the distribution and kinematics of the H I gas suggest that the filament was created by an inelastic collision between Draco nebula and a H I high velocity cloud at V = -180 km/s.
