1A. SOLAR SUMMARY
Activity 07 Jun: R0
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Jun: 101/49

10.7cm/SSN 100/48 100/48 105/54
COMMENT: Solar activity on UT day 07 Jun was at the R0 level,
with no significant flare activity. There are currently no significant
sunspot groups on the visible solar disk. No significant Earth
directed CMEs have been observed in the past 24 hours. A northward
directed CME was visible in LASCO imagery from around 07/0348UT,
but is considered a farside event. The solar wind speed on 07
Jun was mostly steady varying from 306 to 339km/sec, mildly elevated
following yesterdays weak shock. The peak total interplanetary
magnetic field strength (Bt) was 10 nT, and the north-south component
(Bz) range was +2/-7nT, with a period of mildly southward IMF
conditions 00-08UT. There is the possibility of a weak CME impact
early on 08 Jun, which may slightly elevate wind parameters on
08 Jun. Solar flare activity is expected to be predominately
at the R0 level, possibly increasing in the next day or two due
to the potential return of a previously flaring solar region
to the north-east limb. There also appears to be a solar region
behind the south-east limb which is likely to rotate onto the
disk in coming days.

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.
