We propose to continue a monthly imaging program at the 0.9m to determine the nova rate in several galaxies of different Hubble type. Ciardullo et al. (1990) claims that the nova rates in galaxies of different Hubble type are very similar when normalized to the total galaxy K-band luminosity. However, Della Valle et al. (1994) claims the rates to be different by up to a factor of four, with early-type galaxies being deficient in novae. Since nova rates depend on several properties of the stellar population they derive from, one might expect some variations. The observations proposed here will provide much better statistics on several Local Group galaxies than presently exists in order to improve the nova rate estimates in a variety of stellar populations. This data will also be used in a research-based science education program (RBSE) operated by NOAO, wherein middle- and high-school science students learn astronomy and inquiry-based learning skills via research. Students are able to find the novae easily and derive light curves using available image processing software. This request continues the approved program from last year.
