We have observed Jupiter on July 24, 25, 26 and 27, 1994, in thermal infrared, using the French National 10 micron array camera “C10 µ ”, mounted on the Canada‐France‐Hawaii 3.6 meter telescope. The observations were made using both broad‐band and narrowband filters, as well as a Circular Variable Filter (CVF). Two observing programs were scheduled, one concerning atmospheric observations and the other one focusing on seismological observations ( Lognonné et al. , 1994). We present here preliminary results concerning the atmospheric program. The main result 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.
