SUMMARY FOR 22 OCTOBER AND FORECAST FOR 23 OCTOBER - 25 OCTOBER
STATUS INDICATORS SOL:** RED **   MAG:** YELLOW **     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 22 Oct:  High

Flares    Max     Fadeout    Freq.  Sectors
  M8.7    0201UT  probable   lower  E. Asia/Aust.
  M2.7    0517UT  possible   lower  E. Asia/Aust.
  X1.7    1428UT  probable   all    South American/Atlantic

Activity     Moderate to high   Moderate           Moderate
Fadeouts     Probable           Possible           Possible
10.7cm/SSN   215/165            220/170            220/170

COMMENT: A number of C-class flares as well as the listed events. 
AR 12192 (S13E12) continues to grow and produced the X1, M8 and 
M2 flares while the M1 originated from over the east limb. AR 
12193 (N05W29) has also shown growth. The other three spot groups 
are stable. LASCO images show CMEs associated with the M8 and 
M2 events but these appear directed out of the ecliptic plane. 
There appears to be a minor ejection related to the X flare towards 
the east. The solar wind speed declined from a peak of ~600 km/s 
to ~450 km/s with the north-south IMF range +/-5 nT. The leading 
edge of a recurrent coronal hole is located at 56 degrees west 
and should become geo-effective on 23 Oct.

Observed Regional daily pc3 Indices 22 Oct : 
      Darwin              31   (Quiet to unsettled)
      Townsville           0   (Quiet)

      Gingin               4   (Quiet)
      Canberra             6   (Quiet)

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.
