N2 - We report multiperiodicity in five small-amplitude pulsating red giants: RZ Ari, V523 Mon, BC CMi, UX Lyn, and FS Com. For each of these stars, two or three periods recur in each season of our 5000 day database of V observations. The periods and their ratios are consistent with low-order radial pulsation modes. The amplitudes of the modes change significantly on timescales of 1-5 yr; specifically, the amplitudes of the dominant periods vary on timescales of 2000-3500 days. Most often, the amplitudes of the modes in a given star rise and fall in unison.
