SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT

SUMMARY FOR 13 JUNE AND FORECAST FOR 14 JUNE - 16 JUNE

1A. SOLAR SUMMARY

10.7cm/SSN   150/105            140/94             135/89

COMMENT: Solar activity was moderate over the last 24 hours, 
with C-class flares from several regions and an M2 flare from 
region 2087 (S18E41). No Earth-directed CMEs were observed. A 
large CME from 12-Jun appears to be directed too far south to 
reach Earth. Solar activity is expected to be moderate over the 
next 3 days, with a chance of X-class events. Increasing low-energy 
proton flux suggests the possible arrival of remnants of the 
slow 10-Jun CME on 14-Jun. The solar wind speed hovered around 
350km/s, while the IMF Bz component fluctuated between -6/+7nT.

Observed Regional daily pc3 Indices 13 Jun : 
      Darwin               2   (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.

COMMENT: Quiet conditions were observed over the Australian and 
Antarctic regions over the last 24 hours. Some unsettled to active 
periods are possible at high latitudes on 14-Jun with the arrival 
of the slow 10-Jun CME. Quiet conditions are expected on 15-16 
Jun.

COMMENT: Mildly degraded conditions are possible at high latitudes 
on 14 Jun if geomagnetic activity increases due to CME arrival. 
Short-wave fadeouts are possible over the next 3 days.
