Overview of solar-terrestrial environment
between June, 2014 and March, 2015

Shuji Abe[1][1] ICSWSE, Kyushu Univ.

STE Event Report Workshop
In the event report workshop on
Solar-Terrestrial Environments(STE), we analyze observation
data in order to understandcomplex systems in spaceenvironment.
This workshop will take place 2time each year
(September@NICT andMarch@Kyushu).

SummaryIn this analysis period(between June, 2014 andMarch, 2015)…
•Decreasing sunspot number and solar activity
except June and September•Huge active region at October, but nosignificant influence from there tomagnetosphere•Weak magnetosphere responses during cycle
24 continues.
