  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. Some sample
results for EUSO-SPB2 are shown.
