We here propose HST WFC3/IR J(F125W) and H(F160W) observations to image the UV stellar continuum from the host galaxy of a millimeter bright quasar ULAS J1319+0950 at z=6.13. We have obtained ALMA high resolution image of the [C II] fine structure line and dust continuum emission from this object, which reveals intense star formation in the central ~1" (5 kpc) region of the quasar host galaxy. The WFC3/IR observations we propose here will map the rest-frame 1500A~2500A stellar continuum emission from the starburst quasar host. We will measure the UV-based star formation rate and surface density, and compare the distribution of the UV stellar emission to the resolved [C II] line and dust continuum emission from ALMA. This is an important consistency check of the massive star formation inferred from the millimeter observation and will allow us to map the dust extinction and investigate the relation between star formation rate and the [C II] line emission in the extreme AGN-starburst environment. Moreover, the color measured with the two WFC3/IR bands will constrain the slope of the UV continuum, which is sensitive to the local dust extinction, age, and metallicity of the young quasar host galaxy. These will allow a comprehensive study of the distributed star formation in the earliest quasar host galaxies for the first time and, thus, set key constraints on our models of SMBH-galaxy co-evolution at the earliest epoch. This is a six-orbit package to observe a z=6.13 quasar ULAS J1319+0950, and a nearby star for quasar PSF modeling and subtraction, in J (F125W) and H (F160W) bands. The package consists of 5 orbits quasar observations and 1 orbits of PSF star observations. Visit1 : One-orbit observation of the quasar ULAS J1319+0950 in F125W and F160W. We will use a 6-point dither pattern in boths bands. Visit2 : One-orbit observation of the quasar ULAS J1319+0950 in F125W and F160W. We will use the same 6-point dither pattern and POS-TARG offsets as in Visit1. Visit3 : One-orbit observation of the quasar ULAS J1319+0950 in F125W and F160W. We will use the same 6-point dither pattern and POS-TARG offsets as in Visit1. Visit4 : One-orbit observation of the quasar ULAS J1319+0950 in F125W and F160W. We will use the same 6-point dither pattern and POS-TARG offsets as in Visit1. Visit5 : One-orbit observation of the quasar ULAS J1319+0950 in F125W and F160W. We will use the same 6-point dither pattern and POS-TARG offsets as in Visit1. Visit6 : One-orbit observation of a PSF star in F125W and F160W. We will use the same 6-point dither pattern as is used in the quasar observation with different POS-TARG offsets.

To ensure maximum thermal stability (and thus PSF stability) for these PSF-sensitive observations, we request one of the following constraints, if possible and if they do not interfere with the schedulability of other programs. 1) If our observations occur directly after an SAA transit, that the telescope be slewed to our initial pointing before the SAA transit, allowing thermal settling to occur during the transit. 2) Our observations occur directly after observations on a nearby target, to minimize the change in pointing angle (and thus thermal settling time) at the beginning of our observations.
