Abstract: Forecasting Solar Energetic Particle (SEP) fluence, as integrated over an SEP event, is an important element when estimating the effect of solar eruptions on humans and technology in space. Current real-time estimates are based on SEP measurements at a single location in space. However, the interplanetary magnetic field corotates with the Sun approximately 13 • each day with respect to Earth, thus in 4 days a near-Earth spacecraft will have changed their connection about 60 • from the original SEP source. We …
