Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 050 Issued at 0245Z on 19 Feb 2005 This report is compiled from data received at SWO on 18 Feb

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to minor storm levels. Activity was due to the effects of a high speed stream from a geoeffective coronal hole. Solar wind speed at ACE showed an increase to approximately 600 km/s by 18/1600Z and then decreased slightly to 550 km/s by the end of the period.
