10.7cm/SSN   185/138            185/138            190/143
COMMENT: Solar wind fluctuated around 600km/sec for much of the 
UT day, due to coronal hole high speed stream. 

Previously M-flare(s) producing region 9825 is due for return 
to the north-east limb around 7 Mar.

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.
