Images taken with on the University of Hawaii 2.2-meter telescope, with a new 1024x1024 HgCdTe near-infrared array developed by Rockwell International Science Center are available here. 

These images were taken on the night of July 20, 1994, Hawaiian Standard Time, (July 21 UT) by K. Hodapp, J. Hora, K. Jim, and D. Jewitt. These images were taken using tip-tilt guiding, using Io as the guide "star". 

The images are: 
¥ Impact plume from fragment R (21 Jul 05:37:12 UT); 
¥ Plume in a difference image, made by subtracting an image taken at 05:35:40 from the image shown above; 
¥ An image taken approximately 80 minutes after fragment R impact (21 Jul 06:50:03 UT). Io is the bright object in the upper left. This image has better resolution, because Io (the guide "star") was closer to Jupiter when this image was made. 
All images are taken through a filter centered at 2.3 microns. This filter transmits infrared light in the approximate wavelength range 2.2-2.4 microns, where methane absorption in Jupiter's atmosphere makes Jupiter appear to be relatively dark. 

The quick image processing to produce these images was performed by L. Cowie and R. Wainscoat.
