The stellar initial mass function (IMF) underlies all estimates of galaxy stellar masses and star formation histories. There are theoretical reasons and indirect observations to suggest that the IMF varies with galactic environment. We recently demonstrated via main sequence star counts that the Milky Way ultra-faint dwarf galaxies have shallower IMF slopes as compared to the Milky Way over the mass range 0.5 - 0.75 M_sun, providing direct evidence that the IMF depends on galactic environment. However, these observations do not reach the stellar mass at which the IMF in the Milky Way turns over. Determining the presence and location of an IMF turn over in an environment distinct from the Milky Way will directly test theories of low mass star formation and have implications at all galaxy mass scales. We propose to measure the IMF in the ultra-faint dwarf galaxy Coma Berenices, one of the least luminous and most metal-poor galaxies known. Using the WFC3, we will measure the shape of the IMF to a stellar mass of 0.17 M_sun. This extremely low mass limit is enabled by the combination of ComBer's proximity (44 kpc) and WFC3's infrared sensitivity to the light from such cool stars. The proposed observations represent a unique opportunity to cleanly determine the IMF in a significantly different environment than previously possible and will be the deepest direct IMF measurement outside the Milky Way. We will obtain a total of 44 orbits of WFC3/IR imaging in the Milky Way ultra-faint satellite galaxy Coma Berenices. Our goal is to resolve main sequence stars down to stellar masses of 0.17 M_sun in order to determine the stellar initial mass function (IMF) in this galaxy. We will obtain a 2x2 mosaic centered on Coma Berenices in WFC3/IR using the F110W and F160W filters. We will additionally obtain parallel exposures with ACS/WFC in F606W and F814W. We do not request a specific orient angle, however, all visits should be scheduled at the same orient to maximize the sky coverage at the required depth. Visits will consist of 2-3 orbits, with 2 exposures per orbit in a single filter. Within a visit, each exposure will be dithered to obtain good PSF sampling.
