SUBJ: SWS GEOMAGNETIC DISTURBANCE WARNING 21/03
ISSUED AT 2356UT/06 FEBRUARY 2021
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A series of patchy equatorial coronal holes are expected to affect 
the earth for the expected three UT days. Global geomagnetic 
activity is expected to reach active levels with possible minor 
storm periods on 07 February. On 08 Feb, geomagnetic activity 
is expected to decline to mostly unsettled levels. This may be 
followed by an increase in geomagnetic activity as another slightly 
larger equatorial coronal hole is expected to reach a geoeffective 
location on the solar disk. Aurora may be visible on the local 
nights of 7 Feb and 9 Feb from Tasmania.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED 
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
