With the advent of large-scale optical monitoring and exoplanet search programs comma the number of stars with known stellar cycles is growing rapidly. In parallel comma advances in theoretical modeling are revolutionizing our understanding of magnetic field generation in late-type stars. Many questions remain comma however comma and new puzzles have arisen comma such as the discovery of cycles in fully convective stars. X-ray emission is a powerful diagnostic of stellar magnetic activity comma with cycle amplitudes that are much larger and often more regular than in other wavebands. Of the hundreds of stars with confirmed cycles comma however comma only 8 have been monitored in X rays. We request XMM observations of two stars that will significantly broaden the X-ray perspective on stellar cycles.
