Neutron Monitor

Overview & Purpose

Neutron monitors detect high-energy particles from the Sun, including solar energetic particles and solar neutron particles. These particles pose risks to astronauts, can cause failures in space electronics, and disrupt satellites and space-based technologies.

Neutron Monitor Stations

Haleakalā Neutron Monitor Station (HLEA) - in collaboration with the University of New Hampshire Located at 10,000 feet on Haleakalā, Maui. Captures more solar neutron particles due to longer daily sun exposure and minimal seasonal variations. Thailand-Hawaiʻi Monitor (THIMON) - in collaboration with Chang Mai University Installed alongside HLEA to enhance the global neutron monitor network's coverage. Global Importance: The monitors fill a critical 162-degree gap in the global neutron monitor network between Mexico and Thailand. This will help to improve worldwide space weather forecast.

Space Weather Control Center

Established at UH Mānoa to analyze data from neutron monitors. Supports real-time monitoring and forecasting efforts.

Funding & Collaboration

Funded by a $2.5 million NSF grant over four years. Collaborations with University of New Hampshire and University of Arizona.
