Abstract
A new neutron monitor was installed at Juan Carlos I Spanish Antarctic Base (S $62^{\circ}$ $39^{'}$ $46^{''}$, W $60^{\circ}$ $23^{'}$ $20^{''}$, 12 m asl) last January 2019. The Base is located at Livingston Island (South Shetland Archipelago) close to the Antarctic Peninsula. The vertical rigidity cut-off for this new station is estimated as 3.52 GV. This new station (Antarctic Cosmic Ray Observatory) is composed by a BF3-based 3NM64 (ORCA) and 3 bare BF3 counters (ORCB). The neutron monitor is complemented by a muon telescope sharing a common room in a single stack. ORCA and ORCB with the Castilla-La Mancha neutron monitor (CaLMa) are the Spanish contribution to the Neutron Monitor Data Base. Juan Carlos I Base is a summer station, that that it operates only during the antarctic summer. This affects to communications and data transmission implying two different modes of data transmission, one minute resolution data and almost real time in summer and one hour resolution data that is sent once a day. Nevertheless, data with one minute resolution is stored in a NAS hard drive system along the year. First measurements and future plans are presented in this work.
