SUMMARY FOR 22 JUNE AND FORECAST FOR 23 JUNE - 25 JUNE
STATUS INDICATORS SOL:GREEN   MAG:** RED **     ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 22 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 22 Jun:  94/40


1B. SOLAR FORECAST
             23 Jun             24 Jun             25 Jun
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   100/48              95/41             100/48

COMMENT: All regions mostly stable with 12093 (S09 W20) showing 
some slight growth and new region 12096 (N10 E72) numbered. A 
CME was observed on the east limb at 0209 UT and may be associated 
with region 12096. This CME is not expected to be geoeffective. 
ACE data show the 19 June CME is yet to arrive with nominal conditions 
throughout the reporting period.

Observed Regional daily pc3 Indices 22 Jun : 
      Darwin               8   (Quiet)
      Townsville           0   (Quiet)

      Canberra             0   (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.

Date   T index
22 Jun    47

Observed Australian Regional MUFs
   Cocos Island Region:
      Enhanced 25-40% 07-10 UT. Depressed 20-45%
      00, 11-19 UT. No data 20-23 UT. Near predicted
      monthly values at other times. Spread F 17-19 UT.
   Niue Island Region:
      Depressed 20-40% 02-04, 06-15, 21-22 UT. Near
      predicted monthly values at other times.
   Northern Australian Region:
      Mostly depressed 15-40% at Darwin. Near predicted
      monthly values, depressed 20-30% 06, 10-13, 21, 23
      UT at Townsville. Spread F 12-20 UT at both stations.
      Sporadic E at Townsville 05-10 UT.
   Southern Australian and New Zealand Region:
      Near predicted monthly values to 20% depressed.
      Depressions 20-30% at times mostly 08-12 UT. Night
      spread F observed.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values to 30% depressed.

Monthly T index:
Month  T index
May      80
Jun      92
Jul      91

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
23 Jun    60    Near predicted monthly values to 20% depressed
24 Jun    60    Near predicted monthly values to 20% depressed
25 Jun    55    Near predicted monthly values to 25% depressed

COMMENT: IPS HF Communications Warning 31 was issued on 22 June 
and is current for 23-25 Jun. Lower than expected solar flux 
is likely to reduce MUFs below those based on the monthly T index. 
Night communications may be degraded.
