1. Deep Impact July 4, 6 UT Deep Impact 04 July 2005 ~6 UT Image from the Deep Impact spacecraft. http://deepimpact.jpl.nasa.gov/home/index.html

2. IRTF observers Weather Excellent! An observational campaign was conducted by C. Lisse, N. Dello Russo (Johns Hopkins), D. Wooden (NASA Ames), M. Kelley, C. Woodward (U. of Minnesota), D. Harker (UC San Diego), Y. Fernandez (U. of Central Florida). All data to be made public after 6 months.

3. Moments after impact. Image from Deep Impact spacecraft

4. Lisse et al. IRTF/SpeX Using prism mode, R~100. Observed temporal variation after impact.

5. Fernandez, Kelley et al. IRTF/SpeX J-band light curve at high time resolution. 3 slopes apparent. Interpretation not settled yet.

6. IRTF/SpeX Fernandez, Kelley et al. 3 color light curve shows colors get bluer with time.

7. Lisse, Dello Russo, et al. IRTF/SpeX thermal spectrum. Searching for hydrocarbons, but no spectral features seen.

8. Wooden, Woodward, Harker et al. IRTF/HIFOGS Time history of 10 micron flux density (upper plot); HIFOGS spectrum (right plot) showing the color temperature of the dust.

9. Ruch, Woodward, Kelley, Harker, Wooden IRTF/MIRSI Time history of 8.7-12.3 micron flux density. Note the elevated N- band flux density on July 8. This is a natural outburst of the comet.

10. HIFOGS and MIRSI detect similar fluxes during `nominal activity’. Dust emission rises on 29 Jun (burst) and afternoon after impact. The 10 micron data will be combined with other data to model the dust temperature, composition, and particle size.
