Title: Followup of High-Magnification Spitzer Microlensing Events

Abstract: We will use the rapid-response mode of the LCO network to followup high-magnification microlensing events being observed by the Spitzer microlens parallax program. These events have the highest intrinsic sensitivity to planets, but must be followed intensively over the peak of the event in order to capture that sensitivity. We will use LCO observations to find and characterize pm2$ planetary perturbations in these events to measure the mass ratio and scaled projected separation of the planet and also measure finite source effects. By combining these data with the Spitzer parallax data, we will measure the masses of the planets and the distance between the Sun and the planetary system. Through a complete statistical analysis of the Spitzer microlensing parallax sample including these events observed by LCO, we will make the first measurement of the galactic distribution of planets.
