ISSUED AT 2330UT/09 JUNE 2017 BY Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 09 JUNE AND FORECAST FOR 10 JUNE - 12 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 09 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 09 Jun: 74/11
1B. SOLAR FORECAST
10 Jun 11 Jun 12 Jun
Activity Very low to low Very low to low Very low to low
Fadeouts None expected None expected None expected
10.7cm/SSN 74/11 75/13 76/14
COMMENT: Solar activity was very low for the UT day, 9 June.
Very low levels of solar activity is expected for the next 3
UT days (10-12 June) with a chance of C-class flares. No Earth-directed
CMEs were observed in the available LASCO imagery up to 09/2207
UT. The solar wind speed was near its nominal level, gradually
decreasing from 320 km/s to 290 km/s over the last 24 hours.
The IMF Bt was in the range 2-5 nT during the UT day. The Bz
component of the IMF varied between +4 nT and -2 nT, with no
significant periods of southward Bz conditions. The two day outlook
(10-11 June) is for the solar winds to continue to trend near
the nominal levels.

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.

2B. MAGNETIC FORECAST
Date Ap Conditions
10 Jun 5 Quiet
11 Jun 5 Quiet
12 Jun 8 Quiet to Unsettled
COMMENT: Magnetic conditions were again at quiet levels across
the Australian region during the UT day, 9 June. Mostly quiet
and occasional unsettled conditions are expected for the UT days
10-11 June. On 12 June unsettled levels can be reached due to
expected increase in the solar wind speed.
