SUMMARY FOR 14 JULY AND FORECAST FOR 15 JULY - 17 JULY
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN

1A. SOLAR SUMMARY
Activity 14 Jul:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 14 Jul:  78/17

             15 Jul             16 Jul             17 Jul
Activity     Very low           Very low           Very low

COMMENT: Region 1087 (N21E07) produced two x-ray events, a C1.4 
at 1230 UT and a C3 at 2047 UT. The region has the potential 
to produce further, isolated C-class events. The solar wind speed 
increased from 300 to 450 km/s while the north-south component 
of the IMF became disturbed after about 1830 UT, ranging between 
+15 to -18 nT. Solar wind parameters are expected to be somewhat 
disturbed over the next two days due to the effects of a recurrent 
coronal hole.

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 Space Environment Research Center, Japan.
