Abstract
  • Energetic solar neutrons cause electromagnetic showers in Earth's atmosphere. The flux of secondary neutrons produced in these showers may appear as brief enhancements in ground-level count rate data collected and archived by the Neutron Monitor Database (NMDB). Thorough analysis of these enhancements could lead to a deeper understanding of the events involved in their production. Furthermore, it may be possible to characterize a predictive relationship between some attributes of these enhancements and various properties of subsequent proton-precipitated ground-level events. Unfortunately, there currently exist very few records of these enhancements. To remedy this, several analytical methods were applied in attempts to create an algorithm that can consistently locate the fingerprint of these solar neutrons. This paper describes the setup and implementation of these techniques; however, assuming the aforementioned enhancements exist in NMDB data, the techniques' ability to confidently identify such enhancements is found to be less than promising.
