COMMENT: Solar wind data rose 320-440km/sec over UT day, probably 
in association with the gradual entry of a coronal hole wind 
stream. Also, a small discontinuity was observed in solar wind 
data around 12UT, and EPAM data has peaked just above the first 
IPS precusor flux threshold around this time. This appears to 
indicate a the arrival of partial shock signature from recent 
mass ejections. Todays M3 event was from region 17 on the south 
west limb of the sun. Event was CME associated. However due to 
west-limb location of region and predominately westward direction 
of mass ejection, this event is considered non-geoeffective.

of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

COMMENT: IPS Geomagnetic Warning 21 was issued on 4 July and 
is current for interval 5-7 July. Coronal hole induced activity 
expected to produce active conditions particularly on 07 July.
