1A. SOLAR SUMMARY
Activity 06 Mar: R0
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Mar: 143/97
1B. SOLAR FORECAST
07 Mar 08 Mar 09 Mar
Activity R0, chance R1 R0, chance R1 R0, chance R1
Fadeouts Possible Possible Possible
10.7cm/SSN 140/94 135/89 135/89
COMMENT: Solar activity on UT day 6-Mar was R0, with no solar
flares. There are currently four numbered sunspot regions on
the solar disk. Most regions have shown some minor changes in
their trailing areas, however all regions are overall stable.
Solar activity is expected to be R0 with a chance for R1 over
7-9 Mar.
A slow moving CME directed to the solar southeast was
observed from 06/0428 UT which was associated with a filament
eruption shortly prior. This CME may pass close by the Earth
on 9-Mar but is not expected to have a significant impact. No
other CMEs were observed on 6-Mar.
S0 solar radiation storm conditions were observed on UT day 6-Mar.
S0 solar radiation storm conditions are expected over 7-9 Mar.
The solar wind environment on UT day 6-Mar was mostly near background
conditions, The solar wind speed ranged from between 330 to 370 km/s,
currently steady. The peak total interplanetary field strength
(IMF, Bt) was 10 nT and the north-south IMF component range was
+9 to -8 nT. The solar wind environment may become briefly enhanced
on 7 or 8-Mar due to a small equatorial coronal hole. Conditions may
begin to return to background levels by 9-Mar.

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.

08 Mar 18 G0
09 Mar 20 G0, chance G1
COMMENT: ASWFC Geomagnetic Warning 14 was issued on 6 March and
is current for 7-8 Mar. G0 geomagnetic conditions were observed
in the Australian region on UT day 6-Mar. G0-G1 geomagnetic conditions
were observed in the Antarctic region stations. G0 geomagnetic
conditions are generally expected over 7-9 Mar. Isolated periods
of G1 may be possible on over this period due to recent coronal
hole activity combined with a nearby passing CME.
