[Australian Space Weather Forecasting Centre]

SUBJ: ASWFC GEOMAGNETIC DISTURBANCE WARNING 25/43
ISSUED AT 0316UT/11 JUNE 2025
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

Geomagnetic 27 day recurrence patterns suggest G1, chance G2 
conditions are possible at times during the interval 13-14 Jun. 
A coronal hole is currently in the southeast solar quadrant. 
On previous solar rotations the disturbance interval has preceded 
this holes crossing of the solar central meridian, possibly suggesting 
a corotating interactive region ahead of the holes wind stream. 
However, on this rotation the coronal hole has reduced in area 
possibly suggesting a weaker influence for this rotation.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
FROM 13-15 JUNE 2025
