  The Extreme Universe Space Observatory on a Super Pressure Balloon 2, EUSO
SPB2, mission was designed to take optical measurements of extensive air
showers, EASs, from suborbital space. The EUSO SPB2 payload includes an optical
Cherenkov Telescope, CT, which searches above and below the Earth's limb. Above
the limb, the CT measures Cherenkov light from PeV scale EASs induced by cosmic
rays. Below the limb, the CT searches for upwards going Cherenkov emission from
PeV scale EASs induced by tau neutrinos, to follow up on astrophysical Targets
of Opportunity, ToO. Target candidates include gamma ray bursts, tidal
disruption events, and, after the start of the O4 obervation run from Ligo,
Virgo, Kagra, binary neutron star mergers. Reported here is the selection and
prioritization of relevant ToOs from alert networks such as the General
Coordinates Network, Transient Name Server, and Astronomer Telegrams, and the
translation to a viewing schedule for EUSO SPB2. EUSO SPB2 launched on a NASA
super pressure balloon in May of 2023 from Wanaka, NZ.
