SUBJ: ASWFC GEOMAGNETIC DISTURBANCE WARNING 23/23
ISSUED AT 0018UT/06 MAY 2023
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

A CME observed at 4/1048UT in coronagraph 
imagery may have a geoeffective component with an expected impact 
at 06/0600UT +/- 12 hours, although this event is difficult to 
differentiate from other CME activity around the same time. A 
second CME was observed from 05/0824UT that has been analysed 
as geoeffective and may impact from 07/1200UT. In addition to 
the CMEs, during the UT 06-May, a small equatorial coronal hole 
wind stream and southern coronal hole wind stream are expected 
to increase solar wind speeds.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL MASS EJECTION
FROM 06-08 MAY 2023
