COMMENT: Solar activity stayed at moderate levels today. Several 
C-class and one M1.5 (0708UT) were observed today. This M flare 
from new region 1787 on the south east limb was associated with 
a non-earthward directed CME. The flare resulted in HF fadeouts. 
Solar wind speed showed a gradual decrease from around 370 to 
350 km/s during the UT day today and the Bz component of IMF 
varied between +/-4nT most of the times during this period. The 
CME of 30 June may be weakly geoeffective on 4 and 5 July. Solar 
activity is expected to stay at low levels for the next three 
days with some possibility of isolated M-class activity.

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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.
