10 MICRON MAPPING OF JUPITER ON THE CFHT AFTER THE IMPACTS OF COMET-PSHOEMAKER-LEVY-9/

We have observed Jupiter on July 24, 25, 26 and 27, 1994, in thermal i nfrared, using the French National 10 micron array camera ''C10 mu'', mounted on the Canada-France-Hawaii 3.6 meter telescope. The observati ons were made using both broad-band and narrowband filters, as well as a Circular Variable Filter (CVF). Two observing programs were schedul ed, one concerning atmospheric observations and the other one focusing on seismological observations (Lognonne et al., 1994). We present her e preliminary results concerning the atmospheric program. The main res ult is that persistent brightness temperature enhancements still exist several days after the impacts at several wavelengths, corresponding to a long term perturbation associated to the impact sites.
