# SIDC Weekly bulletin on Solar and Geomagnetic activity #
#--------------------------------------------------------------------#
WEEK 563 from 2011 Oct 10
SOLAR ACTIVITY
--------------
Only C-class flares were seen during the week. No Earth directed CMEs occurred.
GEOMAGNETIC ACTIVITY
--------------------
Geomagnetic activity was quiet to unsettled during the week. No active periods
were observed. The unsettled activity was due to a fast speed stream from a
coronal hole on October 15-16. No ICMEs arrived to the Earth.
