This work reports on an attempt towards improving the Relativistic Electron Alert System for Exploration (REleASE): the occurrence of a type-III radio burst as a precondition for a REleASE forecast. REleASE forecasts are based on the detection of early arrival of near-relativistic electrons ahead of more hazardous protons from Solar Energetic Particle (SEP) events. The goal is to allow astronauts on a Lunar or Mars mission sufficient advance warning to reach a radiation shelter to minimize radiation dose exposure. We test a new system that sets a condition of the occurrence of a type-III radio burst, thus adding independent evidence of particle escape from the Sun, with the aim of reducing known sources of false-alarms of the existing REleASE system. The HESPERIA REleASE+ system, which takes advantage of availability of real-time solar radio observations during the passage of STEREO-A by Earth in 2023, has now been incorporated in the HESPERIA framework. We discuss the techniques used for automatic detection of type-III radio bursts preparing for its real-time implementation, the determination of selection criteria for type-III bursts that are candidates for solar proton events in the Earth-moon system, and first results of the combined system.
