SUBJ: ASWFC GEOMAGNETIC DISTURBANCE WARNING 25/46
ISSUED AT 0255UT/13 JUNE 2025
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

Residual coronal hole influence, and possibly weak transient 
CME influence, may cause G2-G3 geomagnetic conditions on UT day 
13-Jun. This is expected to deline on early 14-Jun, but late 
on 14-Jun another coronal hole may possibly connect with Earth, 
or else on 15-Jun. A co-rotating interaction region may be associated 
with this. G1-G2 geomagnetic conditions are possible over these 
days.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 13-14 JUNE 2025
