SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 2330UT/28 JUNE 2013 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 28 JUNE AND FORECAST FOR 29 JUNE - 01 JULY
STATUS INDICATORS SOL:GREEN   MAG:** YELLOW **     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 28 Jun:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 28 Jun: 101/49

1B. SOLAR FORECAST
             29 Jun             30 Jun             01 Jul
Activity     Low                Low                Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   105/54             110/60             110/60

COMMENT: Three, C-class flares, the largest a C7.3 at 0337 UT 
from region 1778 (S17 W01). Region 1777 (S17 W37) also contributed 
(C4.4 at 0159 UT). The CME from 27 Jun is unlikely to be geo-effective. 
SOHO/STEREO images show another CME (~0239 UT) which is probably 
associated with the region 1777 flare. Most of the material appears 
to be directed southwards, out of the ecliptic plane. Any disturbance 
is likely to be mild with the WSA-ENLIL model expecting the disturbance 
on 30 Jun. ACE data show continued disturbance with the IMF north-south 
component ranging between +12 to -13 nT, mostly southward. Wind 
speed ranged between 380-440 km/s.

Observed Regional daily pc3 Indices 28 Jun : 
      Darwin               9   (Quiet)
      Townsville           0   (Quiet)

      Gingin               0   (Quiet)
      Canberra             5   (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.
