From JPL News Release: 2005-091
In addition to the flyby spacecraft, at least 30 telescopes around the world, including Spitzer, Hubble and the Chandra X-ray Observatory, will be watching the dramatic impact.

I'll bet more telescope are tuned in on Temple 1 than the Shoemaker/Levy impact of Jupiter.
