Free format text (please update) Giant HII regions span a luminosity range of 10^39-10^41 ergs s^-1. At the high end of this range are the three luminous giant HII regions in M101, NGC 5461, NGC 5462, and NGC 5471. The luminosities of these regions rival those of nuclear starburst regions. Only low-resolution data are available up to now, hence intriguing phenomena can be diagnosed but not studied in detail. Therefore, we request WFPC2 images of these three giant HII regions in M101, in order to study the structure of the ionized interstellar medium and the properties of the stellar content with the highest resolution. The results will help us understand starburst process and the formation of clusters. Questions ! Free format text (please update) Observing_Description: We will take WFPC2 images of NGC 5461, NGC 5462, and NGC 5471 with the F656N filter for HAlpha images, F675W filter for continuum subtraction from the HAlpha line emission, and F547M filter for an emission-line-free continuum. For NGC 5471 we request additional observation with the filter F673N for a S II line emission image. The clusters in the these regions are brighter than V = 20 mag, so a 2 x 3 min exposure in F547M gives a S/N > 47. For the HAlpha images we use 24 min exposure with CR-SPLIT to optimize the efficiency of the orbit usage. This integration time is comparable to our WFPC2 observations of 30 Dor, so will reach a similar surface brightness levels. The undiluted S II/HAlpha ratio may be 0.5, so we need a whole orbit is needed for the S II image (with filter F673N). Real_Time_Justification: None. Calibration_Justification: !
