  Muon detectors and neutron monitors were recently installed at Syowa Station,
in the Antarctic, to observe different types of secondary particles resulting
from cosmic ray interactions simultaneously from the same location. Continuing
observations will give new insight into the response of muon detectors to
atmospheric and geomagnetic effects. Operation began in February, 2018 and the
system has been stable with a duty-cycle exceeding 94%. Muon data shows a clear
seasonal variation, which is expected from the atmospheric temperature effect.
We verified successful operation by showing that the muon and neutron data are
consistent with those from other locations by comparing intensity variations
during a space weather event. We have established a web page to make real time
data available with interactive graphics
(http://polaris.nipr.ac.jp/~cosmicrays/).
