SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 01/36
ISSUED AT 28/0138Z SEPTEMBER 2001
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A long duration M1 event was observed 27/0855, with an 
unusual xray profile. Coronal mass ejection activity was observed 
to the south-west of the solar disk. The mass ejection to the 
south-west began around 07 UT and was an impressive large partial 
halo cme. However, event associations are difficult, making the 
determination of whether this was front or backside CME activity 
ambiguous. The orientation of the CME suggests it is possible 
that the CME came from from 9628, but optical on disk flare activity 
around this time is not that convincing, considering the size 
of the observed mass ejection.  

Recurrence suggests that active periods can be expected 29-30 Sep.
If the observed CME was a frontside event then storm activity
may be experienced on 29 Sep.


INCREASED GEOMAGNETIC ACTIVITY EXPECTED
FROM 29-30 SEPTEMBER 2001
-------------------------------------------------------------
GEOMAGNETIC ACTIVITY FORECAST 
29 Sep:  Unsettled to active, chance of minor storm conditions.
30 Sep:  Unsettled to Active
