The M 32 field is 4 arcmin to the SE of galaxy center. An M 31 control field 10 arcmin to the NE will also be observed in an identical fashion. M 31 and M 32 RR Lyrae variables will be detected, measuring the fraction of the metal-poor population which is older than 10 Gyr. Accurate periods and luminosities will be obtained for less than 5% of the variables detected. Questions Observing_Description: 6 orbits will be spent on a field 4 arcmin SE of M32 and 6 orbits in a field 10 arcmin NE of this spot. Each orbit will be split into 2 exposures, most of them with the f606w filter, 4 of them (per visit) with f814w. To maximize reliable time baseline for the RR Lyraes, the first and last orbits will be devoted solely to f606w. Frames from different orbits will be spatially dithered to increase resolution, but telescope pointing will not be changed within an orbit.
