FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 13 JULY AND FORECAST FOR 14 JULY - 16 JULY
STATUS INDICATORS SOL:** YELLOW **   MAG:** YELLOW **     ION: GREEN

1A. SOLAR SUMMARY
Activity 13 Jul:  High

Flares    Max     Fadeout    Freq.  Sectors
  M1.1    0317UT  possible   lower  E. Asia/Aust.
  M3.2    1219UT  possible   lower  European
  M5.0    1458UT  possible   lower  South American/
                                    Atlantic

                                    North American

Observed 10.7 cm flux/Equivalent Sunspot Number for 13 Jul:  92/37


1B. SOLAR FORECAST
             14 Jul             15 Jul             16 Jul
Activity     Low to moderate    Low                Low
Fadeouts     Possible           None expected      None expected
10.7cm/SSN    90/34              85/27              80/20
COMMENT: Solar wind sped rose over the past 12 hours to 600km/sec. 
IMF Bz was southward, favouring reconnection with the geomagnetic 
field, from 07-13UT. Solar region 786 produced five M and several 
C class events. SEC reported a westward directed CME associated 
with the M5 flare occurring near 1458UT.

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.
