1A. SOLAR SUMMARY
Activity 04 Jun:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Jun: 105/54

COMMENT: Solar activity has been at low levels during the last 
24 hours. Today's largest flare was a C2.1 flare from region 
2077(S05E03). This flare peaked at 0136UT.Solar wind speed mostly 
stayed around 350 km/s during the UT day today, reaching close 
to 400 km/s for a short while around 0700UT. The Bz component 
of IMF varied between +/-5 nT during this day. Minor coronal 
hole effects may keep the solar wind stream slightly enhanced 
during the next three days. Low levels of solar activity with 
the possibility of M-class activity may be expected during the 
next three days.

Observed Regional daily pc3 Indices 04 Jun :

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: Variable depressions in MUFs were observed due to declining 
EUV levels resulting from a decrease in active regions on the 
Sun. Expect nearly similar conditions over the next three days. 
Note MUFs are expected to remain lower than predicted due to 
this decrease in EUV.

06 Jun    58    15 to 25% below predicted monthly values
07 Jun    58    15 to 25% below predicted monthly values

COMMENT: Variable depressions to 35% observed in the Australian 
region due to declining EUV levels resulting from a decrease 
in active regions on the Sun. Expect nearly similar conditions 
over the next three days. Note MUFs are expected to remain lower 
than predicted due to this decrease in EUV.
