  14. 13. Investigating Cosmic Ray Variation with Semi-Leaded Neutron Monitors and Polar Surveys
    Waraporn Nuntiyakul (CMU)
    06/01/2025, 15:20

    This study presents notable progress in cosmic ray research through both semi-leaded (Changvan) and standard neutron monitor configurations, focusing on the Changvan latitude surveys (2018–2024) and altitude comparisons with the Princess Sirindhorn Neutron Monitor (PSNM). Our findings confirm the spectral crossover pattern in cosmic ray modulation, revealing rigidity-dependent phenomena—drifts...

  15. 14. CMU-ESE Research Activities on Space Weather and Cosmic Rays and its impact
    Siramas Komonjinda (CMU)
    06/01/2025, 15:45

    Chiang Mai University (CMU) has a longstanding history of astronomical research, beginning with the establishment of the Sirindhorn Observatory in the 1980s. Over the years, CMU has expanded its facilities to include advanced infrastructure for monitoring space weather and cosmic rays, such as the Chang Van neutron monitor and the CMU Space Weather War Room. In 2023, CMU launched the Research...

  16. 15. Ionospheric and Magnetospheric Responses to Space Weather
    Suwicha Wannawichian (CMU)
    06/01/2025, 16:00

    Thailand's awareness about space weather has grown significantly in the past decade. It is now commonly accepted that space weather, the dynamics of particles, and radiation outside the Earth can significantly affect human activities on Earth. We have looked at the ionospheric response using GNSS observations during geomagnetically quiet and disturbed times and disturbances produced by the...

  25. 31. Transport of GV Rigidity Solar Energetic Particles in Turbulent and Non-turbulent Interplanetary Magnetic Field and SEP profiles at 1 AU
    Ashraf Moradi (University of Arizona)
    07/01/2025, 11:35

    Ground-level enhancement (GLE) is triggered by GV rigidity solar energetic particles (SEPs). In such high energies (a few hundred MeV/n to a few GeV/n), the characteristic of an SEP events differs from the more common low-energy SEPs at 1 au. We present several numerical studies on how the characteristics of an SEP event depend on parameters of the interplanetary magnetic field (IMF),...

    Sirindhorn Neutron Monitor (PSNM) in Thailand, the South Pole Neutron Monitor, and a
    mobile semi-leaded neutron monitor (Changvan) during a latitude survey. The
    atmospheric and detector simulations accounted for deadtime...
