The selected star-forming regions exhibit a range of strengths and chemical compositions. They span an abundance range from 1/10 (SMC, NGC 5471 in M 101) to 3-4 times solar (CCM 71 and 72 in M 51). IZw 18 (1/30 solar) is in another proposal. Observations with ISOCAM will be considerably more sensitive, more complete and better calibrated than observations with other existing means. The nature and the thermal properties of the hot dust which radiates in the 10-20 micrometer wavelength range are not understood yet, although it certainly contains silicates. This is also true for the carrier(s) of the infrared bands, although there is some agreement that they may be PAHs or related carbonaceous products. Both are likely to be strongly dependent on the UV radiation field and on the chemical composition of the interstellar matter. A comparison of the distribution of their infrared emission with that of the ionized and neutral gas and of "normal" dust should contribute to the understanding their physics and chemistry. Together with coordinated other ISO and ground-based observations, it will also allow to study the structure and the energy balance of these active regions. OBSERVATION SUMMARY Full LW CVF scans will be secured for the brightest HII region in each of the Magellanic Clouds, allowing also a study of atomic lines and extinction. All the regions will be imaged with the following filters: LW2, 3, 4, 6, 7, 8, 10 and the brightest one (30 Dor) with LW1. All targets will be observed with 6" pixels with the exception of 30 Dor in filter LW3 (3" pixels). The elementary integration time will be 2 seconds except for targets in M 101: NGC 5447 and 5471 (filters LW4, 6, 7 and 8: 5 seconds; NGC 5461 filters LW4 and 7: 5 seconds. Beam Switching (CAM03) will be used for strong targets and microscanning (CAM01) for faint targets. The observing procedure consists in a combination of a short beam switch to get the central part and a refernce background far away from the bulk of the galaxy, followed by a raster map. This procedure is done for each filter. The expected S/N ratio is in general larger than 10. <=== scientific_justification ===> Time distribution for autumn launch targets: team top 40% second 30% last 30% CAM: 37020 0 14280 Total: 37020 0 14280 Time distribution for spring launch targets: team top 40% second 30% last 30% CAM: 37020 0 19080 Total: 37020 0 19080 <=== autumn_launch_targets ===> 1, "CAM04", 1.0, "N", "N66(SMC)", 00.95736, -72.44333, 1950, 0., 0.,5120, 0 2, "CAM04", 1.0, "N", "30 Dor", 05.64928, -69.13389, 1950, 0., 0., 5120, 0 3, "CAM03", 1.0, "N", "N66(SMC)", 00.95736, -72.44333, 1950, 0., 0., 5640, 0 4, "CAM01", 1.0, "N", "IC133(M33)", 01.50756, 30.62500, 1950, 0., 0., 1680, 0 5, "CAM03", 1.0, "N", "IC133(M33)", 01.50756, 30.62500, 1950, 0., 0., 890, 0 6, "CAM01", 1.0, "N", "NGC595(M33)", 01.51244, 30.43583, 1950, 0., 0., 880, 0 7, "CAM03", 1.0, "N", "NGC595(M33)", 01.51244, 30.43583, 1950, 0., 0., 1290, 0 8, "CAM03", 1.0, "N", "NGC604(M33)", 01.52878, 30.52889, 1950, 0., 0., 2390, 0 9, "CAM03", 1.0, "N", "30 Dor", 05.64928, -69.13389, 1950, 0., 0., 10350, 0 10, "CAM01", 1.0, "N", "IZW36", 12.39792, 48.76694, 1950, 0., 0., 880, 0 11, "CAM03", 1.0, "N", "IZW36", 12.39792, 48.76694, 1950, 0., 0., 1290, 0 12, "CAM03", 1.0, "N", "CCM71/2(M51)", 13.46056, 48.76694, 1950, 0., 0., 2240, 0 13, "CAM01", 1.0, "N", "N5447(M101)", 14.01189, 54.51167, 1950, 0., 0., 4480, 0 14, "CAM03", 3.0, "N", "N5447(M101)", 14.01189, 54.51167, 1950, 0., 0., 480, 0 15, "CAM01", 1.0, "N", "N5461(M101)", 14.03203, 54.55750, 1950, 0., 0., 3430, 0 16, "CAM03", 3.0, "N", "N5461(M101)", 14.03203, 54.55750, 1950, 0., 0., 730, 0 17, "CAM01", 1.0, "N", "N5471(M101)", 14.04444, 54.63333, 1950, 0., 0., 4830, 0 18, "CAM03", 3.0, "N", "N5471(M101)", 14.04444, 54.63333, 1950, 0., 0., 330, 0 <=== spring_launch_targets ===> 1, "CAM04", 1.0, "N", "N66(SMC)", 00.95736, -72.44333, 1950, 0., 0., 5120, 0 2, "CAM04", 1.0, "N", "30 Dor", 05.64928, -69.13389, 1950, 0., 0., 5120, 0 3, "CAM03", 1.0, "N", "N66(SMC)", 00.95736, -72.44333, 1950, 0., 0., 5640, 0 4, "CAM01", 1.0, "N", "IC133(M33)", 01.50756, 30.62500, 1950, 0., 0., 1680, 0 5, "CAM03", 1.0, "N", "IC133(M33)", 01.50756, 30.62500, 1950, 0., 0., 890, 0 6, "CAM01", 1.0, "N", "NGC595(M33)", 01.51244, 30.43583, 1950, 0., 0., 880, 0 7, "CAM03", 1.0, "N", "NGC595(M33)", 01.51244, 30.43583, 1950, 0., 0., 1290, 0 8, "CAM03", 1.0, "N", "NGC604(M33)", 01.52878, 30.52889, 1950, 0., 0., 2390, 0 9, "CAM03", 1.0, "N", "30 Dor", 05.64928, -69.13389, 1950, 0., 0., 10350, 0 10, "CAM01", 1.0, "N", "IZW36", 12.39792, 48.76694, 1950, 0., 0., 880, 0 11, "CAM03", 1.0, "N", "IZW36", 12.39792, 48.76694, 1950, 0., 0., 1290, 0 12, "CAM03", 1.0, "N", "CCM71/2(M51)", 13.46056, 48.76694, 1950, 0., 0., 2240, 0 13, "CAM01", 1.0, "N", "N5447(M101)", 14.01189, 54.51167, 1950, 0., 0., 4480, 0 14, "CAM03", 3.0, "N", "N5447(M101)", 14.01189, 54.51167, 1950, 0., 0., 480, 0 15, "CAM01", 1.0, "N", "N5461(M101)", 14.03203, 54.55750, 1950, 0., 0., 3430, 0 16, "CAM03", 3.0, "N", "N5461(M101)", 14.03203, 54.55750, 1950, 0., 0., 730, 0 17, "CAM01", 1.0, "N", "N5471(M101)", 14.04444, 54.63333, 1950, 0., 0., 4830, 0 18, "CAM03", 3.0, "N", "N5471(M101)", 14.04444, 54.63333, 1950, 0., 0., 330, 0 19, "CAM01", 3.0, "N", "He 2 10 ", 8.56864, -26.2344, 1950, 0., 0., 1200, 0 20, "CAM03", 3.0, "N", "He 2 10 ", 8.56864, -26.2344, 1950, 0., 0., 1200, 0 21, "CAM01", 3.0, "N", "II ZW 40 ", 5.88469, 3.38528, 1950, 0., 0., 1200, 0 22, "CAM03", 3.0, "N", "II ZW 40 ", 5.88469, 3.38528, 1950, 0., 0., 1200, 0
