Following major storm periods on AUG-18, geomagnetic conditions 
returned to quiet to unsettled levels on AUG 19-20. On AUG-21 
a recurrent coronal hole high speed wind stream caused minor to 
major storm periods, with increased activity persisting for
several days. There was a gradual decline to unsettled 
conditions towards the end of the week.

Disturbed Periods: SEP 1-3, SEP-8, SEP 14-15, SEP 17-19.
