In winter 2018 / 2019, the New Horizons spacecraft will make close (~0.1 au) fly-bys of two small outer solar system bodies (2014 OS393 and 2014PN70). These two objects are among the three that we discovered during our HST based search for a New Horizons Kuiper belt enconter target (now selected; 2014 MU69). These will be our closest fly-by observations, amoung the nearly dozen TNOs that we will observed from NH. They will appear the brightest as seen from NH, be the best resolved (about 10x higher resolution than HST) and will provide the largest science impact among our flyby targets. We will measure their phase curves, their rotational light curves and search for rings and compangion objects. Although the orbits of these two TNOs are amoung some of the best known they are not yet well enough constrained to enable the science. Due to the closeness of the fly-by we must furthre refine our knowledge of their orbits so as to reduce the uncertainty in the projeted sky-plane when viewed from New Horizons. We are requesting 5 HST orbits to further secure the ephemrides of these objects and enable this high-impact science return from the New Horizons Kuiper Extended Mission. Recovery observation of 2 TNOs that are part of the New Horizons encounter plan. The plan here is to aquire 2 visits on each of 2 TNOs to obtain tracking observations. Each Visit is a single orbit and we pack the maximum number of exposures we can manage into the orbit, for WFC/UVIC this about 440s per exposure. Observations should be trailed at the motion rate of the object to get the maximal SNR. We have special trailed PSF software to compute a small correction to the STScI WCS for the images, which we derive from Gaia.
