Lick Observatory Nickel Telescope View of Comet Impact Site 
Evolution

This image, taken 27 July 1994, shows the evolution of the 
impact sites a week after the collision. From left to right 
are the G/S/R/Q2 complex, site N and site H. The large G 
complex is extremely complicated owing to the number of impacts 
all hitting in one area. Site H has grown tails extending both 
northward and southward. Site N is less evolved, but is also 
extending features northward. The features have diminished 
little in intensity over the course of the week and will be 
monitored in the months to come. 

The image was obtained with the 40-inch Nickel Telescope at Lick 
Observatory using a filter 90A wide and centered at 8950A.
