Two mini neutron monitors are installed at Concordia research station (Dome C, Central Antarctica, $75^{ circ}06^{ prime}S$ , $123^{ circ}23^{ prime}E$ , 3,233 m.a.s.l.). The site has unique properties ideal for cosmic ray measurements, especially for the detection of solar energetic particles: very low cutoff rigidity $75^{ circ}S$ . The instruments consist of a standard neutron monitor and a 'bare' (lead-free) neutron monitor. The instrument operation started in mid-January 2015. The barometric correction coefficients were computed for the period from 1 February to 31 July 2015. Several interesting events, including two notable Forbush decreases on 17 March 2015 and 22 June 2015, and a solar particle event of 29 October 2015 were registered. The data sets are available at cosmicrays.oulu.fi and nmdb.eu. |
