“…In addition, in order to optimize the sensitivity of the global NM network for registration of solar neutrons [23], we propose to rebuild the Haleakala NM as well as several new low-latitude (high rigidity cut-off), preferably high-altitude stations. We emphasize that several stations are under construction or are on a final stage of planning [24].…”

Over the years the global neutron monitor network was successfully used to study cosmic ray variations and fluxes of accelerated solar ions, known as energetic solar particles. Recently, it has been used also for space weather purposes, specifically alerts and as a proxy to the related assessment of exposure to radiation (dose). Here, we overview the current status and applications of the global neutron monitor network and discuss its capability to study solar energetic particles, namely assessment of their spectral and angular distribution, during ground-level enhancements, focusing specifically on polar neutron monitors. Here we propose to build several new polar neutron monitor (NM) stations in order to optimize the capability of spaceship Earth to register and provide reliable data for analysis of strong solar energetic particle (SEP) events. We propose to rebuild or open new stations in both North and South hemispheres, e.g. Alert ALRT,

We present the first results of a new redesigned version of the mini-neutron monitor installed on the South African Research vessel, the SA Agulhas II. Measurements taken from the 2019/2020 relief voyages are presented. We show that the instrument is very sensitive to temperature variations when the ambient temperature is below 3oC. This is believed to be an instrumental effect. Additionally, we show the presence of high-frequency interference in the calculated waiting time distributions when the vessel reaches polar latitudes. We show that these periodic variations are only present in the intensity of secondary atmospheric particles and most likely related to the operation of the vessel’s ice radar. We are currently looking at moving the instrument to a more suitable location on board the SA Agulhas II where we will hopefully be able to operate the instrument in a continuous fashion for several years to come.
