Neutral solar wind properties: Advance warning of major geomagnetic storms

The author discusses the prediction of the arrival of coronal mass ejection events (CMEs) at earth by means of monitoring the arrival of energetic neutral atoms (ENAs) which proceed the CMEs arrival by 3 to 4 hours. Large CME have been identified as triggers for large geomagnetic storms, and advance warning of such events has practical value for health as well as electronic communications. ENAs are formed by recombination in the CME, and slowing of the CME in its traverse to the earth allows the ENAs to arrive in advance. The author discusses the magnitude of such arrivals, the energy characteristics of the atoms, and progress on systems to detect such events.
