Drift effects and the average features of cosmic ray density gradient in CIRs during successive two solar minimum periods
A. Fushishita, Y. Okazaki, T. Narumi +14
We deduce on hourly basis the spatial gradient of the cosmic ray density in three dimensions from the directional anisotropy of high-energy (~50 GeV) galactic cosmic ray (GCR) inte…

Precursors of the Forbush Decrease on December 14, 2006 observed with the Global Muon Detector Network (GMDN)
A. Fushishita, T. Kuwabara, C. Kato +13
We analyze the precursor of a Forbush Decrease (FD) observed with the Global Muon Detector Network on December 14, 2006. An intense geomagnetic storm is also recorded during this F…

Drift effects and the cosmic ray density gradient in a solar rotation period: First observation with the Global Muon Detector Network (GMDN)
Y. Okazaki, A. Fushishita, T. Narumi +14
We present for the first time hourly variations of the spatial density gradient of 50 GeV cosmic rays within a sample solar rotation period in 2006. By inversely solving the transp…
