We propose to complete the near-contiguous UV-Visible imaging of the JWST NEP Time-Domain Field comma the best field within the JWST Continuous Viewing Zones to conduct deep and wide extragalactic JWST surveys at arbitrary cadence or orientation. This recently developed comma virgul14. diameter time-domain field near the North Ecliptic Pole (1) is devoid of sources brighter than m_AB virgul 16 mag at 2-4 micron that would deeply saturate JWST-NIRCam comma (2) has the lowest possible zodiacal foreground comma (3) has low Galactic foreground extinction comma and (4) has a wealth of deep ground- and space-based ancillary data from X-ray through radio. Deep UV-Visible HST imaging to m_AB virgul 28 mag exists for the inner virgul9. diameter portion of this field. Completing the coverage of the NEP Time-Domain Field to the same depth comma in combination with extant data comma allows the community todoublePoint (1) Establish a baseline UV-Visible detection image at virgul0.07d_comma FWHM at wavelengths inaccessible to JWST comma and map transients and moving objects in areas of 2- and 3-epoch overlap (2) Identify rest-frame UV-bright objects at z < 6 that would contaminate JWST ultra-high-z galaxy samples (3) Identify galaxies with steep intrinsic UV-Visible SEDs indicative of (weak)AGN comma assess the escape of LyC photons at 2 < z < 3 comma and place limits on that escape and IGM porosity at z < virgul3.5 and (4) Study mass assembly and evolution of all significantly resolved UV-bright galaxies at z < 6 on a .pixel-by- pixel. basis. In order to maximize the scientific return of early-release JWST science comma it is critical to image this field in the UV-Visible while HST is still in its prime and before commencement of JWST observations in 2022.
