SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 15/34
ISSUED AT 0636UT/19 AUGUST 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A large Coronal Hole (CH 683) is located in the solar Northern 
Hemisphere and is taking geoeffective position. A high speed 
solar wind stream emanating from CH 683 is driving a Co-rotating 
Interaction Region (CIR) and this will affect Earth's geomagnetic 
environment over the next 1-2 days. Minor geomagnetic storms 
could occur in the high latitude regions and possibly extend 
into the mid latitudes. The aurora may be visible from the southern 
parts of Australia at the local night hours on 19 and 20 August.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 19-20 AUGUST 2015
