SUBJ: SWS GEOMAGNETIC DISTURBANCE WARNING 19/12
ISSUED AT 0037UT/14 MAY 2019
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

This is an update on geomagnetic warning 19/11 issued at 0512UT/13 
May 2019. Today, UT day 14 May geomagnetic activity is expected 
to be mostly at Unsettled to Active levels and at times may reach 
minor storm levels due to possible a small CME effect. The two 
slow moving CMEs originating from disappearing solar filaments 
are expected to impact the Earth around 05UT on 15 May and 09UT 
on 16 May, respectively. The CMEs originated from the centre 
of the visible solar disk and hence the likelihood of impact 
at Earth is high. The global geomagnetic activity is expected 
to reach Minor Storm levels on UT days 15-17 May. Isolated Major 
Storm levels are also possible, if IMF turned southward for sustained 
periods. Auroral displays over southern Australian regions are 
likely, particularly for Tasmania, on the local nights of 14-16 
May.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL MASS EJECTION
FROM 14-17 MAY 2019
