Аннотация:
We have observed Jupiter on July 24, 25, 26 and 27, 1994, in thermal infrared, using the French National 10 micron array camera “C10µ”, 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.
