Observing ultra-high energy cosmic rays (UHECR) and very high energy (VHE) neutrinos from space is a promising way to measure their extremely low fluxes by significantly increasing the observed volume. The Extreme Universe Space Observatory on a Super Pressure Balloon 2 (EUSO-SPB2), the next, most advanced pathfinder for such a mission, was launched May 13th 2023 from Wanaka New Zealand. The pioneering EUSO-SPB2 payload flew a Fluorescence Telescope (FT) with a PMT camera pointed in nadir to record fluorescence light from cosmic ray extensive air shower (EAS) with energies above 1 EeV, and a Cherenkov telescope (CT) with a silicon photomultiplier focal surface for observing Cherenkov emission of cosmic ray EAS with energies above 1 PeV with an above-the-limb geometry and of PeV-scale EAS initiated by neutrinosourced tau decay. As the CT is a novel instrument, optical background measurements for space neutrino observation are an important goal of the mission. Any data collected during the mission will influence and improve the development of a space-based multi-messenger observatory such as the Probe of Extreme Multi-Messenger Astrophysics (POEMMA). We present an overview of the EUSO-SPB2 mission and its science goals and summarize results as available, from the 2023 flight.

“…Transient and steady source database: The first module of the ToO software is a listening module designed to filter alerts from various alert networks, such as the Gamma-ray Coordination Network (GCN) and the Transient Name Server (TNS). GCN and TNS alerts are available in machine-readable formats [12]. Several criteria determine which alerts are added to a source database: we select alerts corresponding to potential sources of VHE neutrinos.…”

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.

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 observation 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.
