COMMENT: Solar wind speeds have continued to decline over the 
past 24 hours down to approximately 400km/s. Recent CME activity 
is not expected to be geoeffective.

Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

latitudes. Slight depressions are again possible at times for 
mid-high latitudes for 9 May, otherwise mostly normal conditions 
are expected for the next few days.
