The PROSPECT-I detector has several features that enable measurement of the direction of a compact neutrino source. In this paper, a detailed report on the directional measurements made on electron antineutrinos emitted from the High Flux Isotope Reactor is presented. With an estimated true neutrino (reactor to detector) direction of ϕ= 40.8\unicodexB0 ± 0.7\unicodexB0 and θ= 98.6\unicodexB0 ± 0.4\unicodexB0, the PROSPECT-I detector is able to reconstruct an average neutrino direction of ϕ= 39.4\unicodexB0 ± 2.9\unicodexB0 and θ= 97.6\unicodexB0 ± 1.6\unicodexB0. This measurement is made with approximately 48000 Inverse Beta Decay signal events and is the most precise directional reconstruction of reactor antineutrinos to date.
