SUBJ: ASWFC GEOMAGNETIC DISTURBANCE WARNING 23/73
ISSUED AT 0343UT/29 NOVEMBER 2023
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

Several CMEs are expected to impact Earth over 30-Nov and 01-Dec. 
Two CMEs were observed on 27-Dec that were expected to arrive 
on 30-Dec, followed shortly by a very mild glancing blow from 
a third. One or possibly two halo CMEs were observed on 29-Nov 
which are Earth directed. It is likely all or some of these CMEs 
will combine on their trajectory towards Earth, making it difficult 
to pinpoint an exact arrival time, however G3-G4 geomagnetic 
conditions are possible over this period.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL MASS EJECTION
FROM 30 NOVEMBER 2023 TO 01 DECEMBER 2023
