Very-high-energy neutrinos can be observed by detecting air shower signals. Detection of transient
target of opportunity (ToO) neutrino sources is part of a broader multimessenger program. The
Extreme Universe Space Observatory on a Super Pressure Balloon 2 (EUSO-SPB2) Mission,
launched on May 12, 2023, was equipped with an optical Cherenkov Telescope (CT) designed to
detect up-going air showers sourced by Earth-skimming neutrinos that interact near the Earth’s
limb. Presented here is an overview of the sky coverage and ToO scheduler software for EUSO-SPB2. By using the balloon trajectory coordinates and setting constraints on the positions of the
Sun and Moon to ensure dark skies, we can determine if and when a source direction is slightly
below the Earth’s limb. From a source catalog, CT scheduling and pointing is performed to
optimize the search for high energy neutrinos coming from astrophysical sources. Using historical
super pressure balloon trajectories and the EUSO-SPB2 trajectory, sample schedules are described.
