Description
The recent deployment of two new neutron monitors, HLEA and THIMON, at the summit of Haleakalā, Hawaii, represents a significant advancement in the global neutron monitor network. Positioned at 3,055 meters above sea level, these monitors benefit from reduced atmospheric interference, providing high-quality measurements of galactic cosmic rays (GCRs) and solar neutrons. Operational since December 2024, HLEA and THIMON are filling a critical geographical gap in the Pacific Ocean region. Their strategic location offers unique opportunities to compare measurements with other neutron monitors, aiding in cross-calibration efforts and enhancing the reliability of the global network. This presentation will cover the technical specifications of HLEA and THIMON, their initial performance metrics, and the first scientific results. We will also discuss their integration into the neutron monitor database. As part of the broader scientific community’s efforts to maintain and expand neutron monitor capabilities, HLEA and THIMON underscore the importance of investing in new stations, maintaining robust data repositories, and fostering international collaboration.
