Saturn's rings have been observed on July 1999 with CAMIRAS mid-infrared camera mounted on the CFH Telescope. At that time sub-solar and sub-earth planetocentric latitudes were respectively B'=-19 deg. and B=-20.9 deg. Seven filters in the wavelength range 8.5-25 microns were used. As particles cross Saturn's shadow, they cool down and then heat up after eclipse. Thermal inertia and mean particle sizes can be estimated from their heating and cooling rates. Phase angle was 6 deg. so that first minutes of cooling could be observed for the first time. Previous observations (Froidevaux et al. 1981) of the particles heating in the B ring favour low thermal inertia of their surface. Our observations provide new data on thermal cycles for all the main rings A, B and C. Data and preliminary results will be presented.
