SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 15/12
ISSUED AT 0554UT/20 APRIL 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A weak coronal hole is expected to influence the Earth in the 
latter half of the UT day of 20 April and produce slightly enhanced 
geomagnetic activity. A slow moving CME is expected to impact 
the Earth in the latter half of the UT day of 21 April and may 
add to the coronal hole effects to produce mildly elevated geomagnetic 
activity. Mostly unsettled to active levels are expected with 
the chance of minor storm periods primarily at high latitudes.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL MASS EJECTION
FROM 20-21 APRIL 2015
_____________________________________________________________

GEOMAGNETIC ACTIVITY FORECAST
20 Apr:  Initially quiet with unsettled levels in the latter half of the UT day
21 Apr:  Quiet to unsettled with isolated active periods possible in the latter
